Original frame persists in animation

[dstansby]

Describe the bug

Reporting sunpy/sunpy#5967 upstream. See https://docs.sunpy.org/en/stable/generated/gallery/plotting/lineAnimator_examples.html for the animation that looks wrong. I can reproduce this locally too.

To Reproduce

import matplotlib.pyplot as plt
import numpy as np
from mpl_animators import LineAnimator

data_shape0 = (10, 20)
data0 = np.random.rand(*data_shape0)

plot_axis0 = 1
slider_axis0 = 0

xdata = np.tile(np.linspace(0, 100, (data_shape0[plot_axis0] + 1)), (data_shape0[slider_axis0], 1))

ani = LineAnimator(data0, plot_axis_index=plot_axis0, axis_ranges=[None, xdata]).get_animation()

plt.show()
