RTL indention icons need to be flipped

[AlmogBaku]

By clicking the padding button(for indention) the action not works - it warpped the text by "p" element with padding-left insted or padding-right in RTL.

Seems to be broken since 2.5 (2.3.3 used nested <blockquote> tags for indentation).

I've tried to add directionality : "rtl" and directionality plugin to ​TinyMCE fiddle config, and couldn't make indentation work there either.

Seems this should be fixed upstream.

It looks like the icons just need to be flipped here.

Also a few more questions...

• Do we need to flip the undo/redo icons for rtl?
• Maybe these also need to be flipped in dashicons.css. Maybe also worth looking for other icons that might need to be flipped.

21281.2.patch looks good. Thinking it's better to open new ticket if we are going to switch the icons for undo/redo, and perhaps another one for any dashicons that need to be flipped for RTL.

In [31142]:

TinyMCE: fix (switch) the indent/outdent icons in RTL mode so the arrow points at the proper direction. Props avryl, fixes #21281.
