Describe the Issue

See this PR for the full context and discussion:
#580

I think we've settled on a change in messaging for the Toast/Dialog/Drawer documentation rather than any codebase related modifications. Generally idea is we should warn users against the follow scenarios:

1. Don't use a global store in a SvelteKit app within a Load function
2. If you need a overlay feature triggered on init, put it inside a Browser context if (browser) ...

Then linking back to the PR discussion or SvelteKit threads for additional reference.

Are you able to create a Pull Request with the fix?

Yes
