This is not 100% reliable as database connections are closed in a separate
thread according to the documentation:

Rewrite migration 17 without `idb`
...
We ran into issues when doing async operations inside of an IndexedDB
`onupgradeneeded` handler. The errors were ‘The transaction is not active’ or
‘Transaction has finished’. The following documentation confirmed that
transactions are committed/terminated when control returns to the event loop:
Spec

Since the initial database migration is so critical, I decided to avoid `idb`
with promise support for IndexedDB for now, but will reconsider using it for
other tasks in the future to improve readability of IndexedDB code.

Use `while` loop for IDB cursor iteration
...
Previously, I messily combined promises and callbacks because I thought we
were affected by the microtask issue:

ESLint’s `more/no-then` encouraged me to revisit this and it works as expected.
