Bug summary

When calling pyplot.subplots( layout = "constrained" ) after creating a figure causes matplotlib to display two windows instead of one. See minimal code below.

Code for reproduction

#!/usr/bin/env python3

import matplotlib.pyplot as pyplot

figure = pyplot.figure( figsize = ( 6, 4 ) )
pyplot.subplots( layout = "constrained" )
pyplot.show()
