[Regression] [PWA?] Widgets not receiving messages after sleep on Android

### Current Behavior

There has been a change in behaviour of some sort recently, I think probably with the release of 1.15.0. Now, occasionally, on Android if the dashboard is left open and the device left alone for several hours, then on waking the device up the widgets no longer receive updates.

On waking there is no connection failed/recovered popup seen.
Navigation operates normally but widgets are never updated and the widgets apparently do not send messages back to node-red.

I managed to repeat it with a debug build of one of my widgets, and using the remote monitor in Chrome, can see that when a page is opened `mounted` is called and the widget receives its `props` message. On widget-load is never called though, and it receives no further messages. Note that this is not a recurrence of #444 which was triggered by a failure to reconnect after a network failure.

To recover it is necessary to force a page refresh.
