Admin bar styling issues with Opera

[nacin]

In Opera, padding is messed up for the Howdy image, and two search icons are displayed.

Part of this was reported in #18197 (18197#comment:111).

19137.opera-avatar-fix.patch​ does fix the howdy image.

For some reason, Opera 11.52 doesn't display RGBA background. 19137.opera-background-fix.patch​ fixes that.

Replying to SergeyBiryukov:

For some reason, Opera 11.52 doesn't display RGBA background.

Scratch that, 19137.patch​ fixes the icon and the background.

Looking at #15851, seems it should have been #wpadminbar ul li:before.

Opera doesn't seem to like global :before selector.

[SergeyBiryukov]

With 19137.2.patch​, it's also possible to actually enter something into search input (see #19149).

Opera doesn't seem to like global :before selector.

Like I said before, Opera the next IE. :) Patch works, nice catch.

In [19157]:

Fix the global :before/:after selectors for Opera, props SergeyBiryukov, see #19137

Looks good.
