FR: Using Plotly.Fx.hover in callbacks

Discussed in #396

I'm trying to make a stacked graph initiate hover events on all graphs when you hover over one graph. I figure I can do this with an on_hover callback, and a function, but I don't see how I can use the Plotly.Fx module; it does not appear to be available when probing from a browser's debug call or just calling directly in the $fn

Basically I'm trying to recreate the effect seen https://plotly.com/javascript/hover-events/#coupled-hover-events, but for a stacked grid of plots
