plotting fails with document.pyodideMplTarget set #53
Description
I attempted to use document.pyodideMplTarget to set a target element for a plot, and obtained this error message:
File "<exec>", line 59, in tplot
File "/lib/python3.11/site-packages/matplotlib/pyplot.py", line 389, in show
return _get_backend_mod().show(*args, **kwargs)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "/lib/python3.11/site-packages/matplotlib_pyodide/html5_canvas_backend.py", line 450, in show
plt.gcf().canvas.show()
File "/lib/python3.11/site-packages/matplotlib_pyodide/browser_backend.py", line 117, in show
div = self._create_root_element()
^^^^^^^^^^^^^^^^^^^^^^^^^^^

mpl_target.appendChild(div)
^^^^^^^^^^^^^^^^^^^^^^

I've attached my html code for this error. For now, I'm just using the default append behavior.
