Private message send button is disabled after rotating screen
Steps to reproduce:
- Start writing a private message
- Rotate the screen to landscape - the keyboard closes
- Rotate the screen back to portrait - the keyboard is still closed
- Try to send the message - the send button has no effect
- Delete and re-enter the text - the send button works again
Related to #843. @grote I'm guessing this may be fixed already on your 843-landscape-keyboard branch, as some relevant code has changed - could you please test?
