title: Is it possible to track geolocation with a service worker while PWA is not open
body: <p>Is it possible to read from local storage and track geolocation in PWAs with a service worker while app is not open on phone (in background)</p>
  
  <p>So far my research is pointing to no, and I am finding that the PWA needs to be open for location services.</p>
  
  <p>Thank you,</p>
