react + legendonly bug

[alexcjohnson]

Calling Plotly.react from a state with all traces visible: 'legendonly' to a new normal state breaks the plot until a fresh newPlot call.

Separate note: why can't I click the legend lines/symbols to show/hide traces? I have to click the name or the space immediately above or below the legend line, but the lines/symbols themselves don't do it.

This is something to do with uirevision - simply setting all traces visible: 'legendonly' in the initial figure does not trigger this bug.

Hmm, very strange. Using restyle(gd, 'visible', 'legendonly') instead of clicking on the legend items gives the correct result -> https://codepen.io/etpinard/pen/pGpdJP?editors=1010

So yeah, this is consistent with something being up with uirevision.
