1112646 - Can't single-click select from a <select> element any more

Status: RESOLVED DUPLICATE of bug 1082510

(Core :: Layout: Form Controls, defect)

Description

[Benjamin Smedberg]

<select> controls seem to have changed recently in Firefox, making mouse selection worse.

STR:
* Open a page with a select element (such as this bugzilla page)
* left-mousedown on a select element such as "severity"
- the select popup opens here
* while keeping the left button pressed, mouse down over the menu
* lift the left mouse button over the element you want to select

EXPECTED:
* the element that you chose should be immediately selected and the popup should close. This is what happens in FF35, for example.

ACTUAL:
* no element is selected and the popup remains open

This appears to be a cross-platform bug; I have reproduced it on both Windows and Linux.

This is apparently e10s related (the new UI which shows a dot next to the selected item is also e10s-only).

Felipe says this will be fixed by bug 1053981. I'd like to have QA verify that, though.

I can still reproduce the problem on e10s window.
