With the rotation, the above checking are useless because the assumption was a label not rotated.
That said, I have change a little bit the logic for position: 'auto' (default), take the sides nearest to the point. This could be a breaking change but sounds working fine.
I'm going to submit the PR (in draft) in order you can have a look.

@kurkle I have done a preliminary study in order to enable the label rotation. The issue is the callout position calculated automatically:
