Bidi in form/select/option markup

The text in each option item is "W3C ملاعلا ربع".
In RTL context, should appear "ملاعلا ربع W3C".

Only unicode control characters U+202B (RLE) and U+202C (PDF) has effect.

Please, display the menu, select and then click.

First option, no markup, no CSS.
Second option, with attribute dir="rtl".
Third option, with unicode U+202B (RLE) and U+202C (PDF).
Last option, with CSS "direction:rtl; unicode-bidi: embed;".

Note! Firefox has a problem with second and fourth option. RTL markup and CSS do have effect, but only when all options are visible. the selection appear differently before and after click.
