AttributeError occurs when clicking with mplcursors

My code to plot and have labeled lines when I hover them keeps getting an error when click on the canvas. I even tried using the basic example from the mplcursors webpage and the same behavior is apparent. If you're going to run the code to see, you may have to click a line and then a blank part of the canvas.

import matplotlib.pyplot as plt
import numpy as np
import mplcursors

data = np.outer(range(10), range(1, 5))

fig, ax = plt.subplots()
lines = ax.plot(data)
ax.set_title("Click somewhere on a line.\nRight-click to deselect.\n"
             "Annotations can be dragged.")

mplcursors.cursor(lines)  # or just mplcursors.cursor()

plt.show()

Here is the error I get:
