Fire plotly_afterplot after Promise.all callback

[etpinard]

fixes #1341

This test here fails on master.

I'm not exactly sure why though which might me related to #76

Consider:

var gd = document.getElementById('graph')

Plotly.plot(gd, [{}])

gd.on('plotly_afterplot', () => {})

I suspect that on master the Plotly.plot promise is resolved before gd.on('plotly_relayout, /* */) is set. By tucking gd.emit('plotly_afterplot') is the Promise.all callback the Plotly.plot promise is resolved after gd.on.

exactly - in most cases the plotting itself is sync, so your fix here is spot on.

Just wondering, is this only fired on Plotly.plot calls?

Curious, as I'd love to use this event with the React component, but that seems to use either:
Plotly.newPlot &
Plotly.react

Thanks!

Right, plotly_afterplot should be fired when Plotly.newPlot completes. Not sure why that doesn't happen.
