Pop-up misplacement in webpages with frameset elements

Small problem

Bigger problem

in the other direction - the highlighted text is in the brownish shade, which is completely obscured by the popup:

Cause

This page contains an IFrame which contains a Frameset containing two Frames... By removing some of the structural labyrinth, the misplacement disappeared:

I deleted one Frame from the Frameset (without any other modification to the DOM or stylesheets), and the main text body moved to the header area, but the pop-up and highlight are now in correct relative position.

Thanks for the report. I'll look into it. We have to jump through a lot of hoops to translate positions between iframes so I'm not surprised there are cases that are wrong.

I had a look into this and it turns out it's not related to iframes, but <frameset> elements 🤯 You can see the problem still reproduces if you open up the archive page directly:

Talk about a blast from the past.
