First thanks for the incredible minimal framework, i've started using it today and i liked so much, especially the 7kb package :), but i got some issue in SSR.

I'm using SSR with hydrate and hydratable options, when I import a simple Button component inside my entrypoint component, the console show an undefined error, whitout the importation, app work's fine. I don't know if my error is caused by webpack configuration or by any bug.

I cannot reproduce this in REPL so I created a reproduction repo: https://github.com/SorEduard/svelte-ssr-error

Just install dependencies and run npm run start or yarn start

Thank's for the attention.

My env:

I founded the issue, the problem was in the svelte-loader, hotReload option setted to true cause the error. Closing.
