FWIW, this limitation is known and was discussed in the original bug :
This was indeed a known limitation when we started to work on the new implementation of the eyedropper.
Because we're not using XUL anymore, we can't use floating XUL panels (which can extend out of the bounds of the browser) and instead the eyedropper is injected as a devtools highlighter [1] into the page, therefore constraining it to the page's bounds.

I don't think this is a regression worth fixing, and we wouldn't be able to fix it with the new implementation. So marking as WONTFIX based on this.
