Required for the PerformanceMark constructor, which doesn't allow any
mark names that have the same name as an attribute in the
PerformanceTiming interface in a Window context.
This reworks checkboxes to use a tiny 16x16 SDF for the tick icon along
with an antialiased background/border.
The checkbox now works well at any scale, shows the various checkbox
state (enabled, disabled, being pressed), and supports using the colors
from the active system theme and/or the accent-color property.
This builds on the existing ad-hoc ResourceLoader code for HTTP fetches
which works for files as well.
This also includes a test that checks that stylesheets loaded with the
"file" URL scheme actually work.
CORS cross-origin responses in the No CORS request mode provide an
opaque filtered response, which is the original response with certain
attributes removed/changed.
The relevant effect it has is setting the body to `null`, which means
`body_bytes` has `Empty` in the process_response_consume_body callback.
This effectively disables cross-origin linked resources
(e.g. stylesheets).
However, the web actually depends on this, especially for stylesheets
retrieved from a cross-origin CDN. For example, Shopify websites
request stylesheets from `cdn.shopify.com` and Substack websites
request stylesheets from `substackcdn.com`.
This makes this a specification bug, as this code was written from it.
The workaround is to read the actual body from the unfiltered response
and then call `process_linked_resource` from there.
This _should_ be safe to do, as linked resource fetches do not include
credentials (i.e. cookies and the Authorization header), so it cannot
provide personalized responses.
Previously we were using the HTML parse_dimension_value method for the
height and width attributes of an SVG element. These attributes should
however be treated as css properties instead and thus also support
calc() and absolute units so we use the css parser for this instead.
This would previously assert in InlineFormattingContext because we had
an outwardly inline box that wasn't inwardly flow.
Fix this by converting text-based input boxes to inline-blocks. This is
an ad-hoc solution, and there might be a much better way to solve it.
Instead of special-casing FlexFormattingContext in the intrinsic sizing
layout helpers, add FormattingContext::automatic_content_width() and let
each context subclass decide what that means.
No behavior change here, just moving this responsibility.
This fix addresses issue where, if request headers contain
"Connection: keep-alive", we keep socket open without letting client
know that we support keep-alive connections. This can result in a
large number of open and unused sockets.
Before this change `apply_clip_overflow_rect` might crash trying to
access `clip_rect` that does not have value because we currently
support calculation of visible rectangle when `overflow: hidden`
is applied for both axis.
At the moment, we can't resolve CSS calc() values without having a
LayoutNode. The new StyleProperties::line_height() overload was trying
to do exactly that, which led to an assertion.
This patch makes `line-height: calc(...)` behave the same as
`line-height: normal` for now and adds a FIXME.
If the PaintableBox had children, but we didn't hit any of them, we
default to saying that you hit the PaintableBox itself.
However, if said PaintableBox has `pointer-events: none`, we should
say nothing was hit, so that the hit testing can continue.
This fixes an issue where Discord server icons were not clickable.
Previously, empty text boxes would fall back to the min-height: 16px
set on the <input> element. As soon as there is any content they
would usually gain height because the line height of that text is
more than 16px (depending on the font/font-size used).
Now they use height: 1lh for the inner div (which contains the
actual text), which matches the exact height of 1 line of content.
