Repo restack autostash fails while/after pushing a branch

My usual workflow is to push the `main` branch, and while that is happening, restack the repo on top of `main` in a new tab.

After autostashing was added to the restack command, my restacks started failing with this:

```
FTL git-spice: stash changes: stash create: exit status 1
```

[This](https://github.com/injust/dotfiles/blob/main/git/config) is my Git config, if it helps, but I apologize that it's a bit lengthy.
