Esc in VIM mode unfocuses code editor in Vivaldi browser

[drbogar]

Specs

OS: Windows 11 Pro
Browser: Vivaldi 6.1.3035.302 (Stable channel) (64 bites)
CodeMirror version: 5

Bug description

I can't use VIM mode because every time I press Esc, it pops out of the text box instead of just going into normal mode.

To Reproduce

1. Open the codemirror VIM test site in Vivaldi!
2. Click in the code box! You are NORMAL MODE by default.
3. Press i to enter INSERT MODE!
4. Press Esc!

Expected behavior

The code box is expected to react to further inputs of user after return to NORMAL MODE with Esc key.

Additional information

I've tested it in Chrome, Firefox and Edge and I'm experiencing the bug in vivaldi alone.
I've tested it in incognito mode, with all add-ons and ad block disabled and the error is still present.

If this browser doesn't let scripts intercept Esc presses, I don't think there's anything we can do about that.

@marijnh , Seems to work fine here:

[niklasl]

Scripts are able to capture Esc presses in Vivaldi. Vivaldi does however also automatically unfocus the backing textarea. Fortunately this is done sensibly, so it is stoppable by doing if (evt.key === 'Escape') evt.stopPropagation(). I think doing this in onKeyEventTargetKeyDown of codemirror5 Vim mode would solve this.

(One might blame Vivaldi here, but I really appreciate its default behavior, because of my Vim habits. Other browsers may follow suite (maybe Edge has already?), so it makes sense for codemirror to handle this.)

Same thing is happening for Leetcode + VIM keyboard binding
