TypeError: "focus" is read-only (error in console)

[tiropictor]

Annoying message in console appears when this extension is on:

TypeError: "focus" is read-only           [contentscript.js:2:347419]
Ja moz-extension://a432ccf2-09e9-48cb-ae40-c74291cfe98c/contentscript.js:2
Za moz-extension://a432ccf2-09e9-48cb-ae40-c74291cfe98c/contentscript.js:2

Can't really figure out what's wrong, because js is minified and I have no idea which part causes this warning. Warning goes away when extension is turned off.
EXT v.6.0.1
FF 140.0.4 (64-bit)

Yeah, i see this problem too.

Probably it happens in some NPM package. I will try to figure out

At a first sight it looks a problem in react-aria package
