[Feature request] Restore proper controls focus after closing panel

[tempuserr]

It would be cool if focus be restored properly after closing translation panel by ESC from keyboard.

E,g. when I write this text and open panel by keyboard shortcut Alt-T to check some word - now!... and close panel by ESC from keyboard then focus didn't go back to last active control on the page (this post text field/control) to continue writing - I must use mouse and click on text field to go back to editing.
