Should we expose an official version of Fx.hover that works for all subplot types?

Hello,

I recently switched my app from using scatter to scattergl and realized that the Fx.hover method does not work correctly for that plot type. This codepen shows that the change to scattergl breaks the hover call. I did not see this listed anywhere as a gl2d limitation so I wanted to get it out there. I also realize that the plan is for Fx to be removed in the future however I was hoping there may be some plan to amend the hover method to work with scattergl.

A quick look through made it seem like one of the sticking points is that the hover method is looking for a "hoveron" field in the trace which is not present for scattergl. It is then set to an empty string and the hover code moves on without looking for any points to execute the hover on.

Thanks!

Beginne damit, den verlinkten CodePen mit scatter und scattergl nachzubilden; untersuche dann den bestehenden Fx.hover-Einstiegspunkt und wie er das hoveron-Feld des Traces verarbeitet. Kläre, ob das Projekt eine offizielle Hover-API möchte, die alle Subplot-Typen unterstützt, und definiere den Abschluss als konsistentes Hover-Verhalten für scattergl, ohne sich auf eine undokumentierte Einschränkung zu stützen.
