Onebox Twitter embedding failing when URL contains valid Markdown

Possibly a duplicate of this one:

Oneboxing URLs with two dashes

Ok, here’s a weird bug. When an URL contains --, the markdown converts it do – For example, this URL: cs--preview.khanacademy.org https://cs–preview.khanacademy.org If I explicitly insert a link, it works, even though it is rendered incorectly: [https://cs--preview.khanacademy.org](https://cs--preview.khanacademy.org) https://cs–preview.khanacademy.org PS: Hm, linkifying seems to be disabled here on meta, but hopefully the second example makes things clear.

By the way, this is not really about embedding, the link itself does not work, as you demonstrated.
