Reproducible demo

https://docusaurus.io/

Steps to reproduce

Please refer to the video in description. See bottom left for the pressed keys. It happens when the search box is focussed and you press Cmd+Opt+I. It then gets in some broken state and browser shortcuts like Cmd+R also stop working.

Edit: I think probably keydown is being intercepted (by docsearch maybe?) even when meta is pressed, and the extracted key can be Dead:

Expected behavior

The browser devtools open.

Actual behavior

The search box opens with "Dead" as input. It probably shouldn't intercept things when Ctrl or Meta (Cmd) is in modifiers.
