Bug summary

I used layout=compressed to align colorbar and figure, but after I added fig.suptitle the colorbar is not aligned

Actual outcome

If I do not add "fig.suptitle", the colorbar is aligned with the subfigure

import matplotlib.pyplot as plt
import numpy as np

arr = np.arange(100).reshape((10, 10))
fig, ax = plt.subplots(ncols=2, figsize=(4, 2), layout='compressed')
im0 = ax[0].imshow(arr)
im1 = ax[1].imshow(arr)

plt.colorbar(im0, ax=ax[0])
plt.colorbar(im1, ax=ax[1])
plt.show()

If I add "fig.suptitle", the colorbar is slightly longer than the subfigure

import matplotlib.pyplot as plt
import numpy as np

arr = np.arange(100).reshape((10, 10))
fig, ax = plt.subplots(ncols=2, figsize=(4, 2), layout='compressed')
im0 = ax[0].imshow(arr)
im1 = ax[1].imshow(arr)

plt.colorbar(im0, ax=ax[0])
plt.colorbar(im1, ax=ax[1])
fig.suptitle('Title')
plt.show()

Expected outcome

If I do not add "fig.suptitle", the colorbar should still aligned to the subfigure, while added a title above them
