Failed to execute 'drawImage' on 'CanvasRenderingContext2D' when Canvas instance is embedded in the ipywidgets layout

For my project, it is required to embed Canvas from the ipympl backend in the ipywidgets Layout or AppLayout.
It worked perfectly with version 0.7.0, but with all newer versions the plot image is not rendered in the canvas with exception in Crome browser: Error setting state: Failed to execute 'drawImage' on 'CanvasRenderingContext2D': The HTMLImageElement provided is in the 'broken' state.

The minimum example:

import numpy as np
from matplotlib.figure import Figure
from ipympl.backend_nbagg import Canvas as Canvas, FigureManager

class PlotWidget(Canvas):
    
    __num__ = 0
    
    def __init__(self, **kwargs):
        Canvas.__init__(self, Figure(dpi=100, figsize=(6, 5.5)))
        self.resizable = False
        self.header_visible=False
        
        fig = self.figure
        ax = fig.add_subplot(1, 1, 1)
        self.lines, = ax.plot(np.linspace(0, 1, 100), np.linspace(0, 1, 100), 'o-', markersize=2, linewidth=2)
        
        manager = FigureManager(self, self.__num__)
        self.__num__+=1
        self.draw()
    
import ipywidgets.widgets as widgets
from ipywidgets import AppLayout, Layout

class Layout(AppLayout):
    
    def __init__(self, **kwargs):
        AppLayout.__init__(self, **kwargs)
        self.center = PlotWidget(**kwargs)
        if "pane_widths" not in kwargs: 
            self.pane_widths = [1, '650px', '0px']
        if "pane_heights" not in kwargs: 
            self.pane_heights = ['0px', '300px', '0px']

app = Layout()
display(app)

Comienza con el ejemplo mínimo proporcionado que usa el Canvas del backend_nbagg de ipympl dentro de un ipywidgets AppLayout y reproduce el error de imagen rota en Chrome. Compara el comportamiento entre la versión 0.7.0 y las versiones más recientes; se considera terminado cuando el gráfico se renderiza en el canvas incrustado sin la excepción drawImage.
