Do you want to add a comment that this is a workaround, or is this tracked in an issue and planned to be fixed soon after 3.4 release?

Added an inline comment.
We now implement the required underlying methods (copy_from_bbox and restore_region), but there are issues with the double buffering in nbagg, initialization issues, and with updates to the front end being dropped. For mpl3.4.0 over-ride the class property that checks for the required methods until we can fix the issues with blitting. Closes matplotlib#19701
