Bug report

Bug summary

radius range setting does not work for pcolormesh() in log polar coodinates.

Code for reproduction

%matplotlibinlineimportnumpyasnpimportmatplotlib.pyplotaspltr=np.geomspace(1,100,num=10)th=np.linspace(0,360,num=50)th=np.radians(th)v=np.random.rand(len(r),len(th))ax=plt.subplot(1,1,1,projection='polar')ax.set_rlim(1,100)ax.set_rscale('log')plt.pcolormesh(th,r,v)

Actual outcome

Expected outcome

I think the pixels should spread to the outer edge of the circle, and no warnings should be shown.
