Bug report

I have a figure with 2x3 subplots. Each subplot has a title as does the whole figure. However, even when using plt.tight_layout(), the figure title overlaps the subplot titles on the top row. Looking at StackOverflow, this has been a problem for a while.

Code for reproduction

# Paste your code here
import matplotlib.pyplot as plt
fig, axs = plt.subplots(2, 3)
fig.suptitle('ANON-WL0002')
axs[0, 0].set_title('Slice Dice')
axs[0, 1].set_title('Volumetric Dice')
axs[1, 0].set_title('Slice Hausdorff Dist.')
axs[1, 1].set_title('Volumetric Hausdorff Dist.')
axs[0, 2].set_title('All Slice Dice')
axs[1, 2].set_title('All Volumetric Dice')
plt.tight_layout()
plt.show()

Actual outcome

Expected outcome
The 'ANON-WL0002' should be above the subplot titles
