Andreas Kling	dab1fd265d	test-web: Dump stacking context tree in layout test output ... This will allow us to test (and catch regressions in) stacking context tree construction and updates, etc.	2025-07-09 14:36:08 +02:00
Aliaksandr Kalenik	9e232a70c3	LibWeb: Allow descendant boxes to contribute in overflow rect of parent ... ...with inline children. This fixes an issue when we ignore abspos boxes contained by PaintableWithLines while calculating overflow rect size. Lots of layout tests are affected, because now PaintableWithLines has overflow rect. `Text/input/DOM/Element-set-scroll-left.html` is also affected and now matches other browsers.	2025-07-06 17:10:18 +02:00
Jelle Raaijmakers	71665fa504	LibWeb: Scale font size by 1.15 for line-height: normal ... Browsers such as Chrome and Firefox apply an arbitrary scale to the current font size if `normal` is used for `line-height`. Firefox uses 1.2 while Chrome uses 1.15. Let's go with the latter for now, it's relatively easy to change if we ever want to go back on that decision. This also requires updating the expectations for a lot of layout tests. The upside of this is that it's a bit easier to compare our layout results to other browsers', especially Chrome.	2025-05-05 13:15:56 +02:00
Jelle Raaijmakers	c4bb74f40b	LibWeb: Fix and improve float positioning behavior ... Our recent change to get rid of the "move 1px at a time" algorithm in the float positioning logic introduced the issue that potentially intersecting float boxes were not evaluated in order anymore. This could result in float boxes being pushed down further than strictly necessary. By finding the highest point we can move the floating box to and repeating the process until we're no longer intersecting any floating box, we also solve some edge cases like intersecting with very long floating boxes whose edges lay outside the current box' edges. This is by no means the most efficient solution, but it is more correct than what we had until now. Fixes #4110.	2025-03-27 10:56:13 +00:00
