Click events stop firing after slow "double" click (when using beforehover event handler)

Hello,

I'm using the plotly_click and plotly_beforehover events to get the hover label to persist when someone clicks on a data point.

The idea is that after someone clicks a store a reference to the point they've clicked on. Then in the before hover event, if that reference is populated I cancel the hover event.

(I'm doing more than this in the actual code, but this represents the problem).

If you click quite fast, not fast enough to register as a double click, but pretty quickly, as you move the mouse around. Then sometimes that causes the click events to stop being fired.

This seems to happen when there is a point that should have a persistent hover. The hover gets turned off but then no other hovers are displayed. The reference is populated but the user can't click to turn it off. So you get stuck with no hover labels showing up.

Here's a demo: https://jsfiddle.net/mdt6rqck/

It feels like the quick clicking causes some kind of hover state to get stuck? So now the click events can't get through?
