HoverInfo behavior modification

[compostbrain]

Expected Behavior

Most likely HoverInfo should either stay in a fixed position relative to the map or disappear when you scroll away. A separate issue might be to add the ability to dismiss HoverInfo by clicking on it

Current Behavior

HoverInfo stays in a fixed position relative to the browser window rather than the map when you scroll.

Possible Solution

Change the position to be anchored to the map. Add an onclick dismiss action
