- Add a onebox eg: `https://discuss.samsaffron.com`
- Preview shows onebox
- Keep typing, preview hides onebox (yet onebox class is still there)
☹ ☹
Assigning to @eviltrout for next week.

This is not as serious as it seems. jQuery will sometimes return `href` values with a trailing slash for root domains even if the `href` attribute didn’t have that. I assume oneboxing root domains is rare and that’s why we haven’t seen this before.
This commit fixes it:
