1433887 - Events don't seem to bubble from children of a button when they're absolutely positioned

Status: RESOLVED DUPLICATE of bug 1089326

(Core :: DOM: Events, defect)

Description

[Julien Wajsberg [:julienw] (PTO -> Mar 16)]

STR:
1. Open the attachment.
2. Click on the button itself
[OK] Some log should show up in the page.
3. Click on the 2 lines of text "click me I'm fixed" or "click me I'm absolute"
[KO] Nothing happens.

Note that this seems to work as expected in Chrome.

This works also when we use a normal link (<a>) instead of a button.

This is not a recent bug: I ran the testcase in v57 and v52, the bug reproduces in those versions too.

The issue happens with "position: relative" too if the element is out of the button.

Thanks Olli.

I noticed there are 2 different bugs, so you might want to keep this bug.

Bug 1: non-positioned children of a button never see the event. If they have a listener registered, the listener never runs. I believe this is bug 1089326. But the button itself is triggered.
Bug 2: Where there are children of a button that are positioned out of the button, clicking on them has no effect whatsoever. This is what this bug was about.

I realize they're similar: both bugs relate to the fact that a button's children are non-interactive.
