when enable physics/common/physics_interpolation, the behavior of the game becomes very strange.

This might be a duplicate of #93586?

Can confirm that this issue is fixed by the changes I'm working on for #93586.

Here is an even more minimal mrp for anyone who is curious: physics_interp_rotation_bug.zip. I modified it to use gdscript instead of c#, and also updated it so the rotating sprite's transform is set in _physics_process instead of _process.

@akien-mga this can be closed as it was fixed by the changes I proposed yesterday in #93586 which were merged in #93852
