Hi.  
I’m plotting a px.choropleth\_mapbox figure and, as the documentation states, the `hoverlabel bgcolor` property may be set as an rgb/rgba, but the alpha parameter apparently only changes the amount of white in the color, but the label remains opaque and I can’t see the plot behind. I found an answer for R that adding `hovermode = 'x unified'` should work, but it doesn’t for python in jupyter notebook.

rgba set to 'rgba(255,0,0,1)
