This is how benchmark results would change (along with a 95% confidence interval in relative change) if e6fadbf is merged into main:

•   :ballot_box_with_check:cache_applying: 48.5ms -> 48.3ms [-1.09%, +0.43%]
•   :ballot_box_with_check:cache_recording: 770ms -> 768ms [-0.59%, +0.25%]
•   :ballot_box_with_check:without_cache: 1.84s -> 1.84s [-0.81%, +0.16%]

Further explanation regarding interpretation and methodology can be found in the documentation.

@IndrajeetPatil I also updated NEWS.md in main and we have at least two critical fixes in addition to this one so I think we're cut for a patch release.

Thanks, @lorenzwalthert!

Also, tested the following two cases for a good measure, and everything looks good.
Thanks for finding the fix so quickly.
