Recordings should be saved in Indexed DB locally

[soumik-mukherjee]

Is your feature request related to a problem? Please describe.
ATM, the recording data is stored in the browser tab's memory (i.e. part of the DOM tree). This means the user must download and save the file locally before navigating away from the app. What happens is the tab is closed accidentally, or a link is clicked that takes the user away to another page? recordings that were made must not be inadvertently lost.

Describe the solution you'd like
The app must persist the recording without requiring the user to do anything explicitly, beyond the intent of concluding a recording. (i.e. clicks on the Stop button)

Describe alternatives you've considered
Blobs and files are ideally persisted in Indexed DB. Plus just storing is not the end of the line, user's will need a UI to browse through and retrieve the recordings. Indexed DB is the ideal candidate on all counts.
Accessing local file system, without explicit user consent (every time a recording concludes), is a no go. Asking for the consent each time, worsens the experience.
