Try scrolling down the page.
Normally you'd get to the map then find the map starts zooming or panning.
If there's nothing outside the map to get a grip on you could find yourself trapped in the map, unable to scroll the page up or down.
But Leaflet.GestureHandling prevented that from happening.
On Mobile/Touch enabled devices
- The map ignores the mouse scroll wheel.
- The user is prompted to use ctrl+scroll to zoom the map.
- The map ignores single fingered dragging.
- The user is prompted to use two fingers to pan the map.
It brings the basic functionality of Google Maps Gesture Handling into Leaflet.
