Fix backspace/arrow keys in TextEdit on Linux (#5188)

* Closes #5008 * Closes #5182 * Bug introduced in #4912 I suspect this will make IME no longer work on Linux, though I don't know if it ever worked. I rather have backspace/arrows working though. Please help test this (I don't have Linux!) # Tested on * [x] Mac * [ ] Linux Wayland * [x] Linux X11
