[Bug]: pyplot.quiverkey does not work as expected with polar subplots #26748
Description
Bug summary
pyplot.quiverkey does not work correctly in polar plots.
Code for reproduction
import numpy as np
from matplotlib import pyplot as plt
fig, ax = plt.subplots(subplot_kw={"polar": True})
longitude = np.arange(0, 360, 10)
colatitude = 90 - np.ones_like(longitude) * 60
sample_x = np.ones_like(longitude) # Northward
sample_y = np.zeros_like(longitude) # Eastward
q = ax.quiver(np.radians(longitude), colatitude, sample_y, -sample_x, angles="xy")
ax.quiverkey(q, X=0, Y=0, U=5, label='5 units')Actual outcome
Expected outcome
The quiverkey should be a single line rather than a cartwheel.
