This was a really long bug thread, and only skimmed extremely lightly.

This test case behaves as it should in Emacs 29 -- i.e., the *Backtrace*
window appears in the same place every time.

Are there any other things in this bug report that should be done?  If
so, perhaps it'd make sense to open a new bug report to summarise what
should be done?
