Python with the 'TkAgg' backend on macOS crashes out when figure windows are moved #7743
Description
Bug summary
Python with the 'TkAgg' backend crashes out when figure windows are moved around between multiple monitors.
How to reproduce
Create a few figures e.g.:
from matplotlib import pyplot as plt
import numpy as np
def foo():
plt.figure()
plt.plot(np.random.randn(1000), np.random.randn(1000), 'k.')
for n in range(4):
foo()
plt.show()Move the figures between windows, rearrange them, swap between desktops, perhaps close the windows and rerun the script and repeat. There is a very high probability that Python will crash.
Actual outcome
IPython crashes with

libc++abi.dylib: terminating with uncaught exception of type NSException
Abort trap: 6
This is the most common form of stack trace, though more terse errors, such as
called Tcl_FindHashEntry on deleted table
Abort trap: 6
may be encountered.
Expected outcome
This kind of crash should not occur when we simply move windows from one monitor to the other.
