FIX: do not replace the Axes._children list object - #24677
Merged
Conversation
Each Artist keeps a reference to `Axes._children.remove` as `art._remove_method`. If we replace the `_children` instance on the Axes with a different list instance the Artists will not be updated and their remove method will refer to the wrong list. This will cause subsequent failures on the next draw because on remove we reset the `art.axes` and `art.figure` to None. xref https://discourse.matplotlib.org/t/host-subplot-and-artist-remove/23374
