If this issue only occurs in one browser, which browser is a problem?

Describe the Bug

In astro project with TypeScript, running astro build --outDir ../dist writes .d.ts files to the output dir.

The files include types.d.ts from .astro/ but also other types added by plugins, for example icon.d.ts from astro-icon.

This does not happen if we build to the dir ./dist or any child like ./sub/dir. But it always happen when we build to a dir outside the project, like ../dist.

What's the expected result?

The output dir should not contain .d.ts files.

Can you make a minimal project where this happens? It could be a GH repo since you said this can't be reproduced online.

I tested with Astro 4.5.12 for the example projects (building statically and for SSR) and everything is being generated correctly, I got no .d.ts files. Maybe there is something in your Astro configuration or in your tsconfig.json that differs from the example projects and causes this.

Hey, sure, here is the repo with reproduction: https://github.com/m-radzikowski/astro-issue-10610

It's a fresh, clean project with all default options and only one file created in src/content.

Confirming the reproduction. Thanks @m-radzikowski
