web/database/worker/db-worker.js
218 ↗	(On Diff #24167)	this is the line I am not sure how to handle: we can only start persisting and resolve the promise (promise with app request) to let the app proceed and trust that worker will persist data (current one) await this here to make sure it's persisted but this might slow down the main thread in the app

web/database/worker/db-worker.js
141–144 ↗	(On Diff #24167)	We don't have to `export` the data when the key is missing
218 ↗	(On Diff #24167)	What is the downside of using the same approach for all the operations?

web/database/worker/db-worker.js
218 ↗	(On Diff #24167)	I meant a general difference between using `persist();` vs `await persist()` and my concerns are applying to all operations

add debounce

Adding debounce to persisting,
I set up the database for drafts and persist was not called on each character changed but was debounced as expected.

web/database/worker/db-worker.js
141–144 ↗	(On Diff #24167)	in that order flow is complaining: `Cannot call encryptDatabaseFile with encryptionKey bound to key because null or undefined [1] is incompatible with CryptoKey`

web/database/utils/constants.js
8 ↗	(On Diff #24468)	We can probably name it a little different so that it is obvious that it is a duration of debounce.

use _throttle instead of _debounce

Throttling is a great improvement compared to just calling this function but it still might break when db save takes more than 300ms. We should probably handle that case differently.
