+++ This bug was initially created as a clone of Bug #197050 +++

I am posting a clone of bug #197050 as this has been reported for iOS12. Actually the currently we are facing this issue for iOS 14 (14.4.2) and Safari 14.0.3.
The issue is occuring frequently, but non deterministic while we are performing operations in the IndexedDB (Read/Write).

At some point the IndexedDB is in a broken state and cannot be used anymore.
We caught an error "UnknownError: Connection to Indexed Database server lost. Refresh the page to try again."
The DB conenction cannot be recovered without reloading the app/page.
