Tidy up unprocessedRequestWarning in popup panel

[partingscientist]

I found this warning recently in the popup panel.

Obviously I don't mean to nitpick, but perhaps tidying up this warning might not be a bad idea if there's spare time to do so. Left, right, and top margins at the very least perhaps?

Rendering on your side seems broken.

I was updating from 1.41.2 to the latest stable to get that warning. I don't know, maybe it's broken due to such a big version jump perhaps. Must be on my end only.
