"Uncomment" menu item fails on Linux/Wayland/GTK3

[samth]

Selecting text and using the "Racket|Uncomment" menu item does nothing on Linux with Wayland and GTK3. With PLT_GTK2=1 set, it works correctly.

Fixed by merging racket/gui#316 or it is a different issue?

Oh, that would be nice if that did fix it!
