MessageInput: Undo behaves incorrectly
Gajim v1.8.1 on Debian Testing
Text deleted by Ctrl+U cannot be restored with Undo, to reproduce
- Type something in the chat input box.
- Press Ctrl-u. The entire message is deleted.
- Press Ctrl-z to Undo. The deleted text is not restored.
This is annoying when a user is typing out a long message and accidentally hits Ctrl-u.
