ipympl 0.8.2 - ginput() does not work on Jupyterlab / returns an empty array

Describe the bug
I should be able to select data points from a figure and then red crosses are supposed to appear after clicking with the mouse, but nothing happens, an empty array is returned and the figures only appear after the timeout of ginput().

Expected behavior
Figure pops up and I can click with the mouse on the figure to select data points. An array will be generated

To Reproduce

%matplotlib widget 

import matplotlib.pyplot as plt
import numpy as np
t = np.arange(10)
   
plt.plot(t, np.sin(t))
     
plt.title('matplotlib.pyplot.ginput()\
 function Example', fontweight ="bold")
   
print("After 3 clicks :")
x = plt.ginput(3)
print(x)
   
plt.show()

My Platform

Firefox on Arch Linux, latest version after system update.
I tested it on Jupyterlab, I did not test it on Jupyter-notebook.

Comienza ejecutando la reproducción mínima del issue con el backend %matplotlib widget en JupyterLab en Firefox. Investiga por qué plt.ginput(3) devuelve un array vacío y la figura aparece solo después del timeout; se considera terminado cuando los clics del ratón producen las coordenadas y las marcas de cruz rojas esperadas.
