Bug report

Bug summary

Not a bug as much as a change in behavior that causes downstream issues.

#17543 changes the values set for thefacecolors andedgecolors of "unfilled" marker in scatter.

These changes break seaborn, which relies in several places onscatter settingfacecolors for both filled and unfilled markers.

seaborn can work around the issue in a new release, but at the moment there is no user-facing workaround I can suggest, and the changes mean that all seaborn scatterplots with an unfilled marker will be blank.

Code for reproduction

importmatplotlib.pyplotaspltplt.scatter([0], [0],marker="+").get_facecolors()

Actual outcome

With 3.3.0.rc1

array([],shape=(0,4),dtype=float64)

Expected outcome

With 3.2.2

array([[0.12156863,0.46666667,0.70588235,1.        ]])
