Juno produces plotly graphs only in browser, not in plots pane

On Win64, Julia-1.1.0 and all packages up-to-date, I see the following:

  • Using PlotlyJS directly, an Electron window pops up
  • Using PlotlyJS as a Plots backend, a static version of the plot appears in the plot pane, not the interactive clickable version.

I did some reading on this and came across an issue blaming this on a bug in WebIO. Has there been any progress in this area?
