Description Sebastian Zarnekow CLA 2019-09-02 02:49:45 EDT 
Steps to reproduce:

- Create file some.txt
- Write  `foo bar baz` Save, Close, Reopen editor
- Split newly opened editor vertically (or horizontally)
- Select `bar` in the left / top editor
- Backspace
- Try to undo via Ctrl/Cmd+Z

Keybindings work again after selecting the right editor and than the left again.

Any pointer where I should start looking at if I wanted this thing to be fixed?

Is anyone monitoring this inbox? I would be happy to help with this ticket, but I'd need a little guidance for a start.

I believe you should check platform UI git history - watch there for commits related to keybindings, you hopefully fimd some interesting places to start.

I was afraid that this would be the answer. I'll try to dig into it.
