Aliaksandr Kalenik	9d2809146f	LibWeb: Do paint-order traversal in Document::elements_from_point() ... Elements are now collected according to paint order as spec says, replacing the depth-first traversal of the paint tree with hit-testing on each box. This change resolves a FIXME in an existing test and adds a new previously non-working test.	2024-02-14 06:56:22 +01:00
Aliaksandr Kalenik	9c99182b1e	LibWeb: Change StackingContext::hit_test() to accept callback ... This change modifies hit_test() to no longer return the first paintable encountered at a specified position. Instead, this function accepts a callback that is invoked for each paintable located at a position, in hit-testing order. This modification will allow us to reuse this call for `Document.elementsFromPoint()` in upcoming changes.	2024-02-14 06:56:22 +01:00
Andrew Kaster	6a0fe08604	LibWeb: Implement document.elementsFromPoint ... This API seems to be used by WPT for sending synthetic input events. Implementing the naive translation of elementFromPoint to the spec steps for this algorithm turns 4 'tests had errors unexpectedly' and 3 'tests had timeouts unexpectedly' into 1 pass and 7 'tests had unexpected subtest results' on the infrastructure/ subdirectory of WPT.	2024-02-12 11:43:22 -07:00
