Description:
When writing a text and making the start of the trema using shift + ¨^ key, makes the start of the symbol (character underline) and you can make the character correctly. However, some special key (Control,Insert,Delete,Back Space) are not working after that. Space and Shift keep working for writing text. I try reload button, but it gets worse and the symbol trema with underline keep spawning as if it was the text vertical cursor. If the windows is closed and then reopened,it is working normally again.

Steps to Reproduce:
1.Open any draw file
2.Add a new text
3.Click simulatenously on the shift and ¨^ key (use a french keyboard because it doesn't exist in UK US keyboard)
4.Tap on any key to remove the trema underline part.

Actual Results:
Try removing a text or save your file with Control + S or copy file with Control + C ect..., nothing will work.

Expected Results:
Try removing a text or save your file with Control + S or copy file with Control + C ect..., nall this action should work as before.
