Steps to reproduce
- Launch gtk3-demo
- Choose and run "Assistant" (or any application has text entry)
- In text entry, press and hold key 'A'.
Current behavior
Repeat 'a' in text entry.
Expected outcome
The accented character popup window should appear and let user choose an accented character from it. See also: http://osxdaily.com/2017/03/22/type-accents-mac-easy/
