Persistent State using islands-router

[CodingFlow]

I'm trying out islands-router on my SSR + islands app and running into a few issues. The main issue is that context basically does not work: if there are any server components between context provider and user, it does not work (which is the main use-case). So I tried storing signals in a OnceLock, but found that the state from the signals are not rendered when switching pages, even if there is an Effect to update a derived signal (using closure) that reads signals from the OnceLock.

I need a secure enough client-side storage that persists between pages, such as in-memory, for authentication tokens and other less sensitive data. Any ideas on how to achieve this with islands-router or does the islands-router feature need more time to stabilize?

Secondary related issue: clicking links that go to the same page (hashtag <--> same page without hashtag) resets displayed signal values to default, even if signals are stored in a OnceLock, and Effects are not re-run to allow trying to update the values.

Thank you in advance for any help! 🙇
