Log Message
RenderBlock hit testing should ignore PseudoElements
https://bugs.webkit.org/show_bug.cgi?id=105545
Reviewed by Eric Seidel.
Source/WebCore:
Use nonPseudoNode() in hit testing code in RenderBlock and RenderBox so
that when clicking on the box generated by a pseudo element we never
generate a Position for the PseudoElement, but instead for the
generating node.
Test: fast/css-generated-content/block-and-box-hit-testing.html
* rendering/RenderBlock.cpp:
(WebCore::RenderBlock::positionForBox):
(WebCore::isEditingBoundary):
(WebCore::positionForPointRespectingEditingBoundaries):
* rendering/RenderBox.cpp:
(WebCore::RenderBox::positionForPoint):
LayoutTests:
Add test for hit testing on pseudo element generated blocks and boxes.
* fast/css-generated-content/block-and-box-hit-testing-expected.txt: Added.
* fast/css-generated-content/block-and-box-hit-testing.html: Added.
