Start by reading ipympl/backend_nbagg.py at lines 162-170 and reproduce toolbar property access with the reported Python 3.11.3 and ipympl 0.9.3 versions. Check the mixin-style class behavior described in the linked discussion. Done means toolbar properties no longer emit the warning or raise the reported AttributeError.
