Invisible tooltip background

Is there a way to make the tooltip background invisible? If the tooltip is too large, it can block the plot and that inhibits the user from actually interpreting the data. I think this is less of a wishlist thing for me, I’ve been trying for weeks to get around this.

Setting hoverlabel.bgcolor: 'rgba(0,0,0,0)' should do the trick.

Tried that. It just makes a white tooltip, at least with R.

I was digging in plotly.js for some way to force this to be default or to at least change the opacity to be like 50% or something that won’t get in the way.

If you find anything, let me know. I’ll post what I find.
