It seems like the added test also exercises the update-branch. Edit: no, it is not. |

Finally! While fighting the unit system, I realized that I had reused private names... But it was just to change them and everything worked! Reading the Patch-code a bit better, I also was able to trigger updates without units. |
I lost a couple of hours to the exact same issue working on the svg font fallback! |

I think that's just
if stretched != (self._theta1, self._theta2, ...): ...as it's a tuple comparison?

As noted in https://github.com/matplotlib/matplotlib/pull/22678/files#r831735789 you can get rid of the +360.

Now, the correct path is set for
Arcwhich should solve the following.plt.autoscale()fails for partialArc#23329I am still a bit doubtful if this will kill something else and so on, so I've not added tests yet.Also, not sure if this warrants a release note.There is a bit of inefficiency in the implementation as there are basically two paths created: one during draw time and one that is just stored (and used for e.g. 3D, scaling and collections). One the other hand, for multiple draws there will not be a new creation of an
