Steps to reproduce the problem

1. View the post https://mastodon.social/@gvwilson/112294375846907813 and look at the title of the link preview card.

Expected behaviour

Title should begin with text, not excessive whitespace

Actual behaviour

Title contains excessive whitespace before the text

Detailed description

The site this post links to has an… interesting way of marking up their title tags:

While that is ultimately that site’s fault, Mastodon should probably strip the whitespace when parsing it for link previews. It doesn’t, so the result in the web UI is:

The string returned for the card by the Mastodon API (https://mastodon.social/api/v1/statuses/112294375846907813) is even worse:
"title": "\r\n\t\t\r\n\t\t\r\n\t\t\t\r\n\t\t\t\r\n\t\t\r\n\t\tLab Dynamics: Management and Leadership Skills for Scientists, Third Edition\r\n\t"

For comparison, it seems web browsers do strip the whitespace when displaying page titles.
