[bug?] Chart can't handle `<img>` tags in hover HTML

  • upon hovering over a data point in a scatterplot chart, i'd love to show an image in the hover tooltip. from around the web, it seems like this is possible for plotly users outside of Retool, but (being new to both) it's hard to translate plotly solutions to retool. every permutation of <img... in plotly hover-over doesn't seem to do anything.
