Bug report

Bug summary

The error 'FigureCanvasQTAgg' object has no attribute 'manager' is thrown when trying to determine if the toolbar is active using canvas.manager.toolbar.toolmanager.active_toggle["default"]. Im using Qt5Agg as backend here.

mpl.use('Qt5Agg')
plt.rcParams['toolbar'] = 'toolmanager'

This might be a duplicate or similar to #14568

Expected outcome

Return if the toolbar is active or not

Matplotlib version
