641357 - Window resize grippy overlaid on bottom scroll arrow in about:config

Status: RESOLVED WONTFIX

(Core :: Layout, defect)

Description

[Zack Weinberg (:zwol)]

On Mac, in about:config, the window-resize "grippy" (the three diagonal lines in the lower right hand corner of the window) is on top of the bottom arrow for the vertical scrollbar.  It's supposed to be immediately below the bottom arrow, and is drawn that way on all pages I can find except about:config.  This is not merely cosmetic, it makes the bottom scroll arrow unclickable.

Observed with the current FF4 RC (http://hg.mozilla.org/releases/mozilla-2.0/rev/5f8f494a4c29).  I haven't previously looked at about:config on this profile so I have no idea if this is a regression.

(The "Place[ment of] scroll arrows" setting in System Preferences > Appearance does not appear to affect the bug.)

From that range, bug 595180 looks suspicious.  If that's the problem I don't know why it only happens for about:config, but it'll do for an initial hypothesis.

This is not a regression. Bug 595180 was a temporary regression which caused the resize corner to be invisible, but even during that time the invisible resizer made the scrollbar arrow unclickable.
Originally, bug 56488 was about this issue, but didn't fix the case for XUL trees (which about:config uses).

However, in more recent versions of OS X (starting with 10.7), windows no longer show a resizer, and scrollbars don't even have clickable arrows. So we don't need to fix anything for those versions, and we're probably not going to do anything for 10.6, so I'm wontfixing this bug.
