Bug summary

It appears as if CbarAxesBase.toggle_label and therefore, maybe, SimpleAxisArtist.toggle and possibly something else does not work as expected.

Probably related to the colorbar rewrite?

Code for reproduction

https://matplotlib.org/stable/gallery/axes_grid1/demo_axes_grid.html

Actual outcome

The two middle figures have visible tick labels for the color bar.

Expected outcome

No visible tick labels.

Additional information

There seems to be some sort of mismatch between the _axisnum property and the location of the labels. It seems to work if the labels are located at the same side as the colorbar, i.e., right and bottom.
