Uncaught TypeError: 'remove' called on an object that does not implement interface Element.

Get this error in ff.js:1:26922 after clicking on the "Capture Screenshot" button.

Also getting this error - any chance this'll get fixed?

just got the same error. It seems, in my case, that it is due to having the button that triggers the popup inside a shadow root (inside a custom element).
I assume the clicked element is targeted using document.querySelector('[data-feedback-fish]'), which would return nothing.

edit: nevermind came from a search, so my vanilla JS bug might be irrelevant to React.
