That's really interesting.  I'm not aware of a deliberate change or
fix, I would be very keen to know if a particular commit that addresses
this is ever identified, so we can learn and perhaps lock in the
correct behaviour with a test.

Not that I'm suggesting such tests in production, but if anybody here
can reproduce this well enough and has the time to do a git bisect,
either from the old working to the first failing version or from the
first failing version to the new working one that would be awesome.
