Bug report

Bug summary

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

Code for reproduction

%matplotlib inline

import numpy as np
import matplotlib.pyplot as plt

r = 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.
