Hiya,

Hitting an issue during git rebase. I am starting to suspect git is possibly
getting confused between main and submodule repos. I noticed this with a
self-compiled git 2.54, but I compiled git v2.55 just now, and seem to hit
the same issue still. Full bisect at the end of the message.

Did you by any chance also test the "master" branch? There's been some
fixes to the commit graph that weren't released as part of Git 2.55 yet,
so chance are those could fix the issue for you.

The first-order issue, trying to rebase a work/foo branch which is tracking
origin/master.  There's only one commit difference, a commit that changes
two submodule pointers:

Do you by any chance have a minimal reproducer? That'd help us
tremendously to reproduce and then fix the issue if it wasn't already
fixed on "master".

Thanks!
