The show() method doesn't seem to work.

Hello everybody! I used show() to re-show a plot that was closed. In Julia 1.8.3 it doesn't seem to work anymore.
x = plot(rand(10), rand(10))

close the window

show() # out: empty
x # out: 1-element Vector{PyCall.PyObject}:
PyObject <matplotlib.lines.Line2D object at 0x7faecfddfd30>
show(x) # out: PyCall.PyObject[PyObject <matplotlib.lines.Line2D object at 0x7faecfddfd30>]
display(x) # out: equal to x

Note: I had to install PyCall with the ENV["PYTHON"]="" option

That's not how Matplotlib works.

If you are using the GUI, then closing the figure deletes it.

If you are using some other interface, e.g. vscode or IJulia/Jupyter, then you can call display(fig) on the figure object. However, the return value of plot is not the figuer object. You can get the figure object from x[1].figure or gcf().

I am using bash terminal. When I type x[1].figure, the output in the terminal is: Figure(PyObject <Figure size 640x480 with 1 Axes>), but without showing the graph. When I type gcf(), a blank figure appears. I remember re-displaying the graphics (Julia 1.7.2) with just the show() command.
