868420 - Select box not showing drop-down indicator when using Mac OS X 10.7 overlay scrollbars

Status: RESOLVED DUPLICATE of bug 869314

(Core :: Widget: Cocoa, defect)

Description

[Emanuele Alimonda]

Attachment: Test case

Last Firefox Nightly build is unable to show the drop-down indicators in <select> boxes that have certain styles set (such as background colors, borders), when using the OS X 10.7+ overlay scrollbars.

This appears to be related to bug #636564 (it started happening after it landed)

Steps to reproduce:

- Set "Show scroll bars" to "When scrolling" in System Preferences -> General.
- Load the attached test-case, or visit any site with styled <select> boxes.
- Compare the rendered page with older Firefox builds, or with Safari.

Tested on a 2011 MacBook Pro running OS X 10.8.3, but I suspect it affects any Mac running OS X 10.7+, with the above described settings.
