Mx8 - Then switching to full screen the typing locks. 

After upgrading to Mx8 (8.12.5) it is no longer possible to type text when switching to full screen.

After some random button clicking it is possible to type again. But this is not a nice workaround for end-users who are used to edit large texts in full screen for some years now.

I really hope this will be looked into as there is no other widget available with the same functionality.
