Ctrl-A does not work, it will just reset the entire text to "a".
Other keybinds also don't work, it looks like `charTyped` is called after `keyPressed`
is called, making it "type" the character after executing the shortcut.
Tested on Ubuntu 18.04 LTS and Ubuntu 20.04 LTS on Minecraft 1.15.2 and 20w22a.
Updated description and attachments.
I have added a video showing how to reproduce the issue
