Markers move erratically while zooming on mobile

Given a Leaflet map, if you initialize the map, add a circle marker, and invoke the following:

map.dragging.disable();
map.dragging.enable();

Then when you “pinch-to-zoom” on mobile via touch, the markers on the map move erratically while zoom is in progress, snapping back to the correct position after the zoom is complete. This makes for an ugly user experience.

Replicated on Leaflet latest (1.0.0), on Android Chrome, and Chrome on a MS Surface Pro 3 running Windows 10 (using the touch screen.) Cannot replicate on desktop using a scroll wheel.

For now, we’ll keep the flag _simulated private in simulated events, but consider making it public when/if we get any feedback on anyone using this outside of the Leaflet codebase.
