Meeting registration URLs have invalid og:image meta tags, which leads to sub-optimal link previews:
$ curl https:// us02web.zoom.us/meeting/register/xxxredactedxxxx
[…]
<meta property=“og:image” content=“https://us02web.zoom.usnull”/>
<meta property=“og:image” [… same again, can only post one link …]
[…]
Meta tag is duplicate and invalid, I take it that shouldn’t have the null at the end
