 Browsers can't know if an event listener, like `touchStart` will prevent
 scrolling, so they always wait for the listener to finish executing before
 scrolling the page. Making them passive allows for scrolling to continue
 properly.

 See [https://web.dev/uses-passive-event-listeners/ this doc] for further
 explanation.
