Cancel event propagation on replication swap.
Cancel event propagation on replication swap.

Previous implementation called e.preventDefault() but did not stop upwards
propagation - the click event would therefore trigger navigation to the main
database panel. jQuery calls preventDefault and stopPropagation
when false is returned from an event handler so just do that here.
