829623 - FF 18.0 no click event on transform'ed element with overflow-y:scroll child

Status: RESOLVED DUPLICATE of bug 829921

(Core :: Layout, defect)

Description

[Dmitry]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_2) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.101 Safari/537.11

Steps to reproduce:

I have rather complicated html structure, where transform and overflow-y:scroll properties are present. I also have a click listener on a div which works perfectly in FF 17.0.1 and is broken in FF 18.0.0.

You can see everything here: http://jsfiddle.net/turbokuzmich/DYmKJ/

When I click on a word I expect "a" to be alerted. When the box is not scrolled everything is fine both in FF 17.0.1 and in FF 18.0. But when I scroll down at least 20px and click on a word in FF 18.0 click event is not triggered. FF 17.0.1 works correctly.


Actual results:

Clicking on a word does not alert "a" when the box is scrolled down.


Expected results:

Clicking on a word should alert "a" in all cases.
