Bug summary

pyplot.quiverkey does not work correctly in polar plots.

Code for reproduction

importnumpyasnpfrommatplotlibimportpyplotaspltfig,ax=plt.subplots(subplot_kw={"polar":True})longitude=np.arange(0,360,10)colatitude=90-np.ones_like(longitude)*60sample_x=np.ones_like(longitude)# Northwardsample_y=np.zeros_like(longitude)# Eastwardq=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.
