Bug summary

Two subsequent scatter plots produce incorrect output when calling first scatter with [0], [0] argument. Other arguments for first scatter plot (eg. [1], [1]) seems to produce correct output.

Code for reproduction

import matplotlib
import matplotlib.pyplot as plt

plt.scatter([0], [0])
plt.scatter([3], [3])
plt.savefig(f'test_v{matplotlib.__version__}_{matplotlib.get_backend()}.jpg')
