Svelte docs + sandpack

[YousefED]

@SkaterDad I was able to fix the sandpack issue you ran into. After some debugging I found the trick was to add an explicit "svelte" dependency in the package.json. I think this is either a bug in a new version of Svelte, or a sandpack bug. Anyway, the workaround works for now.

Interesting. I hadn't tried specifying an older Svelte version.

I tried svelte: ^3 and svelte:latest to no avail. The rest of the code looks pretty similar to what I had attempted.

Can you explain the significance of putting fragment: "xml in the SyncedStore init?

I just joined your Discord as SkaterDad#5213.

As for promotion in the Svelte community, the Svelte Society Twitter account seems to retweet lots of neat stuff. There's a Made With Svelte site as well that promotes projects regularly.

Removed! Is only needed for the rich-text demo, but that doesn't use svelte atm
