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

Describe the Bug

When running astro build and setting --outDir to a directory outside of the current project directory, these extra files get generated (both just containing export default new Map;).

Sometimes, also settings.json and data-store.json files get generated. Usually they don't, but occasionally they seem to show up as well.

None of these files show up when normally building into the dist folder, or building into a different folder inside the project folder. My project doesn't use content collections.

What's the expected result?

It should be consistent whether these files get generated or not.
