Does hoverTooltip support returning multiple tooltips within the source function?
I know multiple hoverTooltip extensions will merge ( This allows multiple tooltips over the same range to be "merged" together without overlapping. ), but from the documentation and types it seems like only one Tooltip can be returned from each hoverTooltip extension.
The types show that that is not possible. You could add two tooltip providers or have your tooltip show multiple bits of information in a wrapping DOM element.
