Bug report

Bug summary

plt.subplot eats my subplots. But it doesn't completely digest them, since they are still there, just not shown.

Creating a subplot grid withplt.subplots and in addition adding aplt.subplot removes those subplots from the grid, which are under the newly created subplot.
Creating the additional subplot viafig.add_subplot does not remove them.

Code for reproduction

import matplotlib.pyplot as pltfig, ax = plt.subplots(2,3,                       subplot_kw={"label" : "A"},                        gridspec_kw={'width_ratios':[1,1,3]})ax[0,2].plot([1,2,3])axi = plt.subplot(133, label="B")axi.plot([7,6,5], color="red")axi.axis("off")plt.show()

Actual outcome

Expected outcome

The expected outcome would be the same as withfig.add_subplot:

axi = fig.add_subplot(133, label="B")axi.plot([7,6,5], color="red")axi.axis("off")
