Bug summary

When using a polar coordinate system the plot title overlaps with the axis labels. This worked in 3.9.4 and broke with 3.10.0. This commit broke it:8abe308 via#28300

Code for reproduction

importmatplotlib.pyplotaspltplt.polar([0,1], [0,1])plt.title('My Title')plt.savefig('output.png')

Actual outcome

The title overlaps the axis labels

Expected outcome

The title should be above the axis labels

Additional information

• This bug happens with the new 3.10 version, but with the 3.9.4 version
  I performed a git bisect using this:

 git bisect start

git bisect good v3.9.4

git bisect bad HEAD

a small test scriptcheck.py - there's probably a better way, but that's what I came up with. (Note that the issues also comes up when not using `bbox_inches='tight', but this way it was easier to bisect, since I could instrument the image size)

importmatplotlib.pyplotaspltfromPILimportImagedefmain():plt.polar([0,1], [0,1])plt.title('My Title')plt.savefig('output.png',bbox_inches='tight')withImage.open('output.png')asimg:size=img.sizeifsize!= (453,464):return1else:return0if__name__=='__main__':raiseSystemExit(main())

finally,

git bisect run python3 check.py

After a few steps it yielded this suspicious commit:8abe308 (cc@rcomer) which was merged in#28300
