Additional context
I observed the issue a long, long time ago and attributed it to a small bug. Well it's still here so I decided to report on it! :)

Hi, this issue is a duplicate of #6857. That issue also includes some gdb dumps. Would it be an idea to merge your findings into that issue instead via a reply? This also has the effect of reordering the original issue in the Recently updated sort order.

Alright, did that. :)

Would love to see this resolved eventually... Turns out I posted about this in 2020 too, so this issue is far from new.

The issue is a duplicate. This issue provides little additional value to #6857. It might be better to cluster the conversation on that issue instead, since it already contains a whole lot of context.
