Bug summary

PaddedBox https://matplotlib.org/stable/api/offsetbox_api.html#matplotlib.offsetbox.PaddedBox doesn't look like it is working properly.

Code for reproduction

import matplotlib.pyplot as plt
from matplotlib.offsetbox import PaddedBox, AnchoredText

fig, ax = plt.subplots()

at = AnchoredText("foo",  'upper left')
pb = PaddedBox(at, pad=1, patch_attrs={'facecolor' : 'r'}, draw_frame=True)

ax.add_artist(pb)
fig.show()

Actual outcome

Expected outcome

Red box is at same location as text.

Additional information

It seems like the sizing is working OK (using a longer string will change the size accordingly), but that the positioning is not working.

Also, not passing pad leads to an error, so it should probably be 0. as default rather than None.
