Editing a post with at least 2 revisions on the separated page (just open "edit" link below the post in the new window) shows the "Rev" combobox:
The main issue here is using the word "Rev" on the same line as combobox. This looks inconsistently with the rest fields like "Title", "Body" etc.
If sometimes anybody will want to change "Rev" to "Revision" there will lead to the broken design:
I suggest to move the "Rev" into individual line, this will fix the design issue on Russian interface sites, and make the page view more consistent.
