Selecting data on a graph is not reliable

Hello.

I'd like to report some issues with data selection and filtering in SandDance (it happens in a web version on https://microsoft.github.io/SandDance/app/ as well as Azure Data Studio extension). IMO, this feature works counterintuitively and feels flaky. Sometimes, all it takes is a one click, and the data point gets selected. Sometimes you have to make several clicks or double clicks for it to finally work. Sometimes it gets stuck somehow - data point is already selected (colored purple), but filtering in a data menu doesn't apply no matter what. I have to reselect different data points and go back to the needed one.

There is also a separate problem with selection when SandDance graph is exported into html file. In that environment selection is broken completely, and js console contains several types of errors:
