For unscrolled viewports (already at 0, 0), we can short-circuit here
and avoid doing a synchronous relayout of the page.
This avoids a bunch of synchronous layouts on Speedometer3's NewsSite
(Nuxt version) subtests.

I've also split the `Document::has_focus()` method for clarity. Actually
implementing the "has focus steps" turns out to be quite involved so
I've left it for now.
These callbacks are evaluated synchronously via JS::Call. We do not need
to construct an expensive RootVector container just to immediately
invoke the callbacks.
Stylistically, this also helps indicate where the actual arguments start
at the call sites, by wrapping the arguments in braces.
This fixes the frame-ancestors WPT tests from crashing when an iframe
is blocked from loading. This is because it would get an undefined
location.href from the cross-origin iframe, which causes a crash as it
expects it to be there.
This adds a basic settings page to manage persistent Ladybird settings.
As a first pass, this exposes settings for the new tab page URL and the
default search engine.
The way the search engine option works is that once search is enabled,
the user must choose their default search engine; we do not apply any
default automatically. Search remains disabled until this is done.
There are a couple of improvements that we should make here:
* Settings changes are not broadcasted to all open about:settings pages.
So if two instances are open, and the user changes the search engine
in one instance, the other instance will have a stale UI.
* Adding an IPC per setting is going to get annoying. It would be nice
if we can come up with a smaller set of IPCs to send only the relevant
changed settings.
The intent is that this will replace the separate Task Manager window.
This will allow us to more easily add features such as actual process
management, better rendering of the process table, etc. Included in this
page is the ability to sort table rows.
This also lays the ground work for more internal `about` pages, such as
about:config.
We previously had PropertyOwningCSSStyleDeclaration and
ResolvedCSSStyleDeclaration, representing the current style properties
and resolved style respectively. Both of these were the
CSSStyleDeclaration type in the CSSOM. (We also had
ElementInlineCSSStyleDeclaration but I removed that in a previous
commit.)
In the meantime, the spec has changed so that these should now be a new
CSSStyleProperties type in the CSSOM. Also, we need to subclass
CSSStyleDeclaration for things like CSSFontFaceRule's list of
descriptors, which means it wouldn't hold style properties.
So, this commit does the fairly messy work of combining these two types
into a new CSSStyleProperties class. A lot of what previously was done
as separate methods in the two classes, now follows the spec steps of
"if the readonly flag is set, do X" instead, which is hopefully easier
to follow too.
There is still some functionality in CSSStyleDeclaration that belongs in
CSSStyleProperties, but I'll do that next. To avoid a huge diff for
"CSSStyleDeclaration-all-supported-properties-and-default-values.txt"
both here and in the following commit, we don't apply the (currently
empty) CSSStyleProperties prototype yet.
This is not really a context, but more of a set of parameters for
creating a Parser. So, treat it as such: Rename it to ParsingParams,
and store its values and methods directly in the Parser instead of
keeping the ParsingContext around.
This has a nice side-effect of not including DOM/Document.h everywhere
that needs a Parser.
Instead of just putting in members directly, wrap them up in structs
which represent what a URL blob entry is meant to hold per the spec.
This makes more obvious what this is meant to represent, such as the
ByteBuffer being used to represent the bytes behind a Blob.
This also allows us to use a stronger type for a function that needs
to return a Blob URL entry's object.
Interestingly, the spec has a note saying:
> window.postMessage() performs StructuredSerializeWithTransfer on
> its arguments, but is careful to do so immediately, inside the
> synchronous portion of its algorithm. Thus it is able to use the
> algorithms without needing to prepare to run script and prepare
> to run a callback.
But there is no note about the deserialization steps. In any case, we do
need callbacks enabled here.
Instead of storing all storage objects in static memory, we now
follow the the spec by lazily creating a unique Storage object
on each document object.
Each Storage object now holds a 'proxy' to the underlying backing
storage. For now, this proxy is simply a reference to the backing
object. In the future, it will need to be some type of interface
object that stores on a SQLite database or similar.
Session storage is now correctly stored / tracked as part of the
TraversableNavigable object.
Local storage is still stored in a static map, but eventually this
should be factored into something that is stored at the user agent
level.
There are essentially 3 URL parsing AOs defined by the spec:
1. Parse a URL
2. Encoding parse a URL
3. Encoding parse a URL and serialize the result
Further, these are replicated between the Document and the ESO.
This patch defines these methods in accordance with the spec and updates
existing users to invoke the correct method. In places where the correct
method is ambiguous, we use the encoding parser to preserve existing ad-
hoc behavior.

As part of this, I noticed we incorrectly were setting the "is popup"
flag on the Navigable instead of the BrowsingContext. I've fixed that
and removed the erroneous flag from Navigable.
These interfaces are exposed on *, meaning it should work for workers
and our newly added shadow realm global object by being stored on the
universal global scope mixin.
The MessagePort one in particular is required by Cloudflare Turnstile,
as the method it takes to run JS in a worker is to `eval` the contents
of `MessageEvent.data`. However, it will only do this if
`MessageEvent.isTrusted` is true, `MessageEvent.origin` is the empty
string and `MessageEvent.source` is `null`.
The Window version is a quick fix whilst in the vicinity, as its
MessageEvent should also be trusted.
Resulting in a massive rename across almost everywhere! Alongside the
namespace change, we now have the following names:
* JS::NonnullGCPtr -> GC::Ref
* JS::GCPtr -> GC::Ptr
* JS::HeapFunction -> GC::Function
* JS::CellImpl -> GC::Cell
* JS::Handle -> GC::Root
The main motivation behind this is to remove JS specifics of the Realm
from the implementation of the Heap.
As a side effect of this change, this is a bit nicer to read than the
previous approach, and in my opinion, also makes it a little more clear
that this method is specific to a JavaScript Realm.
