Right now there is a one hour idle timeout, then it will shutdown and close the indexedDB. The reason is it is quite possible to have too many tabs lying around and I am not comfortable to have many tabs writing the same indexedDB. Periodic polling will not work on mobile anyhow. It is better just to refresh the tab by hand.
