During the loading state, the cards are clickable and lead to /wiki/Undefined. That seems unintended.

QA
- Load https://en.wikipedia.beta.wmflabs.org/wiki/Special:Nearby
- Click "Show nearby pages"
- Click one of the cards quickly before they load.
Expected: No change
Actual: I am navigated to https://en.wikipedia.beta.wmflabs.org/wiki/Undefined
