• Status: RESOLVED

Test-case

CSS rules using :hover are not applied if the element is in the visible overflow of a region (-webkit-region-overflow: auto; and overflow: visible).

In contrast, :hover on normal overflowing content is applied.

Reproduction:
In the attached test case move the mouse over the blue word ("overflows")

Expected:
The blue word should become white on a green background.
The word "PASS" (in green) should be displayed above the gray square.

Actual:
Blue word does not change color. Nothing appears above the gray square.

Still repros on today's nightly (r151543)

Patch containing test for :hover and JS events on the visual overflow of a region

This problem has been fixed by https://bugs.webkit.org/show_bug.cgi?id=118665. After that patch lands, these new tests can be landed as well (the tests fail on the current implementation, without the 118665 patch).
