RTL: Themes screen layout issue in Firefox

See the screenshot.

Can't reproduce this in Firefox 28 on OS X.

In case it's not clear from the screenshot and the patch, this is caused by .theme.active .theme-name being 1px higher than other .theme .theme-name elements. The "Active" word somehow triggers this difference.

The patch simply makes sure the elements have consistent height that doesn't interfere with floating blocks. .theme .theme-name would probably make more sense for that, see 27779.2.patch​.

Okay, at least it doesn't break anything. But still can't see this on a clean install in FF 28 in OS X and Windows 8.1, with only $text_direction = 'rtl'; or Arabic language. Height is always 18px.

Could not trigger this with Arabic language files either, only with he_IL.

Reproduced when I set the height of the active theme name to 19px.
