Won't this happens when a user closes VK, or VK is moved to another display?

This will be also called when a user closes VK by |EnsureCaretNotInRect|. Should
I change the name?

On second thought, let's keep it.

   // TextInputClient). The edit command will take into account any OS-specific,
   // or user-specified, keybindings that may be set up.
