web/database/sqlite-data-handler.js
31 ↗	(On Diff #27488)	this key is deleted as in any other case by the worker on the `CLEAR_SENSITIVE_DATA` action - there is a task for improving this when eg. something will go wrong with worker (ENG-3610)
web/database/utils/db-utils.js
50 ↗	(On Diff #27488)	in this case we care only about desktop safari to avoid running this code on mobile

web/database/sqlite-data-handler.js
20 ↗	(On Diff #27488)	we have two options: Call this function only on desktop safari Call this function always and return a null result for non desktop safari and here is option 2, but now I think that this was bad decision, updating this to option 1
web/database/utils/db-utils.js
50 ↗	(On Diff #27488)	we do not support database on mobile at all so it's no need for `CryptoKey`
