waitforbuttonpress in jupyter %matplotlib widget #496

Closed shcrela closed 2 years ago

shcrela commented 2 years ago

Describe the issue

It seems that a call to waitforbuttonpress hinders the rendering of the figure in the notebook. (However, the figure shows up in the log console)

Trying the example from matplotlib gallery Define a triangle by clicking three points reproduces the issue.
Other interactive backends do not show this problem (tried with qt and tk)
