:/regex syntax picks stash entries over regular commits

What did you do before the bug happened? (Steps to reproduce your issue) I ran git stash push, which created the stash entry "On main: dark mode". Then I committed changes before noticing an oversight with the previous commit. I wrote the fix and ran git commit --fixup :/dark

What did you expect to happen? (Expected behavior) The fixup commit should have referenced the previous commit.

What happened instead? (Actual behavior) It referenced the stash entry.

What's different between what you expected and what actually happened? I cannot autosquash the commit that refers to the stash entry. I suggest adding an option to prefer (older) regular commits over (newer) stash entries when specifying a commit with the :/regex syntax. In any case I think it's a bug for the --fixup option to readily produce a commit that does not work with the --autosquash option which it seems it was designed for.
