Alignment buttons doesn't work if there is no content in editor under RTL
|Reported by:||Tomer||Owned by:|
When starting to compose a new post, and clicking on the alignment buttons right away, the user may not see the alignment change.
Steps to reproduce:
Using RTL WordPress, compose new post/page, and click on the left align button.
Text is still starting on the right edge of the editor.
After adding non-aligned content, the text goes to the right position. This is caused because the box element has no specified size, and can be fixed by either setting size on html .mceContentBody or removing the float:right from the element.
