Describe the bug

In the reset function inside the TooltipHandler, it is required to have the PopupMenuHandler plugin loaded in the graph, otherwise the tooltip will never show. PopupMenuHandler is required to check whether isMenuShowing is true. In my opinion it should be handled differently, for example by checking if isMenuShowing is true only when the PopupMenuHandler is present, but I don't know if this is an expected behaviour.

To Reproduce

Steps to reproduce the behavior:

1. Use an instance of BaseGraph
2. Add TooltipHandler plugin (without adding PopupMenuHandler)

Here it's a super basic stackblitz.

Expected behavior

Tooltips should be visible regardless of PopupMenuHandler, which covers another feature.
