[REQUIRED] Describe the problem

When starting my Firebase app up in Safari, I get the following error:

It has to do with the HeartBeatService

I went on research and got the following findings:

• The error happens in this function:

  firebase-js-sdk/packages/app/src/heartbeatService.ts

  Line 82 in 734fdcd

  async triggerHeartbeat(): Promise<void> {

• The error "UnknownError: Error looking up record in object store by key range" is mentioned in the IndexedDB repo, in these two lines:
  https://github.com/WebKit/WebKit/blob/eb072c37fe4eb37704d87b163dd4e9318cd83c5d/Source/WebCore/Modules/indexeddb/server/SQLiteIDBBackingStore.cpp#L2177 and
  https://github.com/WebKit/WebKit/blob/eb072c37fe4eb37704d87b163dd4e9318cd83c5d/Source/WebCore/Modules/indexeddb/server/SQLiteIDBBackingStore.cpp#L2337

So my bet: it is an issue with IndexedDB on Safari
