Sync web-platform-tests PR 11760 into mozilla-central (this bug is closed when the sync is complete). PR: https://github.com/web-platform-tests/wpt/pull/11760 Details from upstream follow. Xiaocheng Hu <xiaochengh@chromium.org> wrote: > [LayoutNG] Fix hit test clipping by fragmented border with round corner > > Current NG hit test code decides whether a hit test location is clipped > by rounded border by adding border radius to all four corners and then > compare with the hit test location. This is wrong if the box is > fragmented, where it may have only two or zero rounded corners. > > This patch changes HitTestClippedOutByBorder() to take the above into > consideration.
