Thanks for tracking this down! In the future, if we break down-stream packages, I think the bug-reports should come to us first (or at least concurrently) as we should not be breaking down-stream packages! |

#10776 changed the logic inside
Patch.contains(), and in particular includes the lineIf this evaluates to
None, then the proceeding logic doesn't work and raises an error. This has broken scrolling/zooming plots made with custom projections in Astropy (astropy/astropy#8545). I presume this is because there is a customPatchsomewhere along the line who's path doesn't contain any codes.This fix just checks if
self.get_path().codes == None, and if it is applies the old logic that was used before #10776 - not sure if this is the long term fix, but in the short term it should be fine.
