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

No response

Describe the Bug

1. Start dev server (astro dev)
2. Change slug of an article
3. See that both the old and the new slug work and are shown in getCollection powered lists
4. Optional: Change the slug again and see more duplicates appearing
5. Restart the dev server
6. See that only the new slug exists

Happens in the most basic Blog example as well.

What's the expected result?

After changing the slug, the old one should instantly not be available any more (just like it is after a restart of the dev server).
