`$props.id()` output format clashes with Server Side Include format

[brittharr]

Describe the bug

When SSIs are turned on in Nginx the server tries to parse <!--#text--> -- which is the same format output during SSR when $props.id() is used. Nginx can't parse this and the default is to print [an error occurred while processing the directive] in the html (replacing Svelte's hydration comment <!--#s1-->)

Would it be possible to change the format of the props_id() renderer output? Maybe like <!--$? That seems safe in the corresponding props_id hydration code too?

The current workaround is to not use this feature and pass ids as a prop to each component instance, but it would be nice to be able to use $props.id()

(I assume this is also an issue with Apache, etc. as they have the same SSI format but I've only observed it with Nginx)
