Describe the bug

Hi, the change from here

https://github.com/sveltejs/svelte/pull/17052/files#diff-e8cd30cfb0931b1ce87fcfc5d783f30effd1334222b69437f33e32eccbf48faaR74

introduced in

breaks ssr snapshots.

It would be cool if we could introduce a compiler option to make hashes in test environment stable in a similar way to cssHash option.

Reproduction

create serverside rendered app.
and snapshot ssr rendered result
