... and it should not.

The visualization of plots in matplotlib change afternapari_matplotlib has been imported. Global settingse.g. here should not be modified by a napari-plugin. Consider programming napari-pluginsside-effect free.

To reproduce:

import matplotlib.pyplot as pltimport numpy as npimage = np.random.random((3,3))plt.imshow(image)

import napari_matplotlibplt.imshow(image)

The same can be observed when not importingnapari_matplotlib but instead opening a viewer wherenapari-stress is installed, because starting the viewer importsnapari_stress and this importsnapari_matplotlib in the background. A napari-plugin should not modify how things are displayed in jupyter notebooks. It's kind of evil usage of global variables.
