Clicking 'Minecraft snapshot 18w48a' in the launcher redirects to Not found page

The bug

Clicking the 'Minecraft snapshot 18w48a' preview in the launcher, redirects you to https://minecraft.net/en-us/article/minecraft-snapshot-18w48a but that's an empty page that returns the error 'Not found'. It should redirect to https://minecraft.net/en-us/article/minecraft-snapshot-18w48b.
