Interactive pan & zoom with facets

[tkorvola]

Interactive panning and zooming in a Jupyter notebook (with the notebook backend) only affects the facet being manipulated. If the facets are constrained to use the same scale, which is the default, other facets should also be updated to maintain this constraint. With, e.g., scales='free_y' all x axes and the manipulated y axis should be affected.

I have not tried the notebook backend but I am surprised that pan & zoom even work at all.
