In case it's helpful, I set debug-on-variable-change as you 
suggested but was bitten by the bug without triggering the 
debugger.

I was alerted to the bug bite when I noticed some folded content 
after the ellipsis on two headlines, both of which folded and 
unfolded without issue (modulo the content after the ellipsis). 
In both cases, the content after the ellipsis consisted of links 
from an Org table, and just those links.  When I fold the parent 
of a misbehaving headline, the links follow the fold and show up 
after the ellipsis of the parent.  The headline that would not 
unfold did not have content after the ellipsis.

I have some ideas about what might have triggered the problem with 
links after ellipses and will check systematically when I find 
time.

Let me know if you have questions.

All the best,
Tom
