I exported a small part of my SVG from Illustrator, and used a circle to animate along a motion path.
The start and end of the animation work fine, though when an arc is introduced, the circle does not follow the center of the path anymore, but rather seems to have its top aligned with the path instead.
I've tried adding alignOrigin: [0.5, 0.5] though that doesn't help.
A bonus question is why I have to add align: self.
If I don't do that, the motion path's coordinates seem to be interpreted as coordinates relative to the circle, instead of absolute coordinates. (as it seems to jump mostly to the right and slightly downwards, presumably the same as the first `M` command of the motion path)
