test_mplot3d:test_quiver3d broke unintentionally #5531
Description
In #5307, where I am lowering our testing tolerance down to zero, I am discovering a few recent changes that slipped through because the tolerance on our tests was too high.
This test was broken in 72819e9.

def test_quiver3d():
fig = plt.figure()
ax = fig.gca(projection='3d')
x, y, z = np.ogrid[-1:0.8:10j, -1:0.8:10j, -1:0.6:3j]
u = np.sin(np.pi * x) * np.cos(np.pi * y) * np.cos(np.pi * z)
v = -np.cos(np.pi * x) * np.sin(np.pi * y) * np.cos(np.pi * z)
w = (np.sqrt(2.0 / 3.0) * np.cos(np.pi * x) * np.cos(np.pi * y) *
np.sin(np.pi * z))
ax.quiver(x, y, z, u, v, w, length=0.1, pivot='tip', normalize=True)
I don't think this change was intentional, so we need to figure out what in 72819e9 is unintentionally causing this change.
