Double-clicking on this plot shouldn't cause a jump: https://codepen.io/nicolaskruchten/pen/yvwOJK

Per @alexcjohnson:

I’m looking at https://github.com/plotly/plotly.js/blob/master/src/plots/plots.js#L1675
it might be enough to rearrange that and say something like if(marginsChangedStuff) { if(replotting) { autoRangeAllAxes } else { Plotly.plot } }
