Build warning incorrectly triggered by comment mentioning trailingSlash in +page.svelte

[ouksal]

Describe the bug

I'm trying to use trailingSlash = 'always' in src/routes/+layout.js, as described in the docs:
https://svelte.dev/docs/kit/page-options#trailingslash

However, during npm run build, I get this warning:

src/routes/arrival/+page.svelte
export const trailingSlash will be ignored — move it to +page(.server).js/ts instead.

Reproduction

After some debugging, I discovered that the warning was caused by a comment inside /routes/arrival/+page.svelte that included the word "trailingSlash". Simply removing that comment resolved the issue.

I'm not sure why the build process interprets a comment as an actual export. Possibly a bug in the static analysis?
