Would it be possible to do some experiments/debugging:
- Can you reproduce the issue with 6.1.85 upstream itself?
- If so can you try the current 6.1.87 (as of time of writing), does
the issue reproduce there?
- If it's still happening, can you try to bisect the changes between
6.1.76 and 6.1.85 to identify the culprit?

Salvatore
