Persist/Pin Custom Tooltips, Allowing for Interaction

I would benefit from allowing users to interact with my custom tooltips directly. Currently, as a user mouses around an area with custom tooltips available, if they move the mouse over a tooltip, it doesn't persist and will either redraw at the new mouse location or show the tooltip for a new parent visual filter context. I would like to see this behavior change to prevent additional updates until the user mouses out of the tooltip. By persisting the tooltip, it would allow me to add interactive elements to the tooltip (inspecting tooltip visuals, clicking bespoke navigational buttons).

Similarly, with this ability, it would seem natural to offer the ability to pin an open tooltip to prevent closing it, and allow the user to possibly move it to a specific portion of the window.
