[Australis, Windows Hi
DPI] button icons can be completely hidden but still be on toolbar and not in overflow menu if window resized/width decreased
Nightly and Aurora 20140313 on Windows 8.1 Pro (OS level font size 125%) When the browser window's width gets decreased, it is possible that the icon of a button gets completely hidden, but some of clickable area is still available (see screenshot). In my humble opinion, the button should get added to the overflow. E.g. after the icon getting partially hidden, or at a threshold (like 50%).
Can you provide STR? On OS X and Linux, we have a recent regression bug filed, where the QA person who reported it said it's not reproducible on Windows, so...
(In reply to :Gijs Kruitbosch from comment #1) > Can you provide STR? 1. Create new profile and launch it (window opens not maximized). 2. Reduce window width.
Summary: [Australis] button icons can be completely hidden but still be on toolbar and not in overflow menu if window resized/width decreased → [Australis, Windows HiDPI] button icons can be completely hidden but still be on toolbar and not in overflow menu if window resized/width decreased
I expect this is a core bug with overflow events, considering that I can't reproduce on 100% DPI but can on 125% (and Jared reproduced on 200% DPI).
Jared said he's looking at this. :-)

I looked for the regression range and this has been present since Australis merged to mozilla-central. http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=beddd6d4bcdf&tochange=ba9ecdea3a90 I think this has something to do with overflowing at a slow pace, because that's the only way that I can reproduce it. My guess is that our calculations for determining if something is overflowing don't trigger if it's only a couple pixels, whereas if you resize the window quickly then this bug doesn't appear.
