Frequent false positive merge conflicts

[bernhold]

Hi, thanks for your action!

I'm trying to use it to create an integration branch -- every time we get a PR or a push to master, we merge them into a "preview" branch. Sometimes it works as it should, but frequently, it fails, supposedly due to merge conflicts. But in nearly all of these cases, we're quite confident there's no merge conflict -- we're adding a brand new file or changing something that no other PR touches. And if we manually rebuilt the preview branch, it would be fine.

I'm wondering if you've seen this kind of behavior in other settings with this action?

Looking at the code, it is hard to see how it could go wrong here, but my colleagues and I are at a loss to understand what's happening. Thanks for any help.
