--- Comment #29 from mrschmidt at google.com ---
We are seeing new issues with iOS 13 and believe that the patch for this issue may be one of the causes. It appears that the following sequence of operations is now possible:

1) The Firestore SDK opens a new IndexedDb transaction/
2) The Safari tab goes in the background.
3) WebKit terminates the network, which stops the IDBServer (https://trac.webkit.org/browser/trunk/Source/WebKit/NetworkProcess/NetworkProcess.cpp#L2117)
4) The app goes back in the foreground and resumes its operation. Firestore tries to use the transaction it opened in step 1 and receives "Attempt to get a record from database without an in-progress transaction"
