Shouldn't we return the value in this try/catch block?

I'd say we should return it after the try / catch block. Seems like in this branch we no longer return it at all in this function.

Pushed a fix 👍 The return statement must have got lost during a git add -p when I wanted to commit the changes as two commits.

I can't think of a rational reason to need to run it multiple times 👍

Fixes issue in React strict mode where local autosave notice appears twice, reported by @ntsekouras here: #47703 (comment)
The notice is created in
useEffect, and on mount, React strict mode runs effects twice.I fixed this by giving a stable ID to the notice, instead of making it unique on each call. If the notice is created for the second time, the previous one gets removed. The unique ID was never really needed -- this is the kind of notice that should appear only once.
