If a user is scrolling through their traveler card profile they reach the Handshake network and start moving that around instead of scrolling through the page. This is extremely confusing to users who aren't tech savy enough to realize what's going on when suddenly their handshake network has disappeared and they can't scroll the page anymore.

What is the expected behavior or new feature?

When touching and dragging on the handshake network with a single finger the interaction should be ignored by the network, and instead scroll the page. It should also flash the "Use two fingers to move the map" message that appears on other maps using this same feature like the map view in OPR review.

When touching and dragging on the handshake network with two fingers the interaction should be used to zoom/pan the network around.

What is the motivation / use case for changing the behavior?

To be more easily understood by users who just are trying to scroll the page.
