New Tumblr embeds about iframely

[essential-randomness]

For people looking for a fix, you can copy this custom plugin I developed: master...essential-randomness:iframely:tumblr-at-final

[iparamonau]

Thanks, and apologies for not paying attention. The Tumblr's URL shortener correctly redirects our cloud to the proper location, no need for that plugin. I feel that you might try playing with the proxy configuration as in PROXY:[...] and add for example curl as the user agent for app.link domain, and you'll get a proper redirect too.

In fact, I checked our config, and indeed we use Chrome UA as otherwise we get a in-app link redirects:

{
            re: [
                /^https?:\/\/(?:[^\/]+\.)?app\.link/i,
            ],
            user_agent: 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/104.0.0.0 Safari/537.36'
        }

If you're going to keep your plugin, please make sure you return cb(null); instead of simply return null;. I realize you have it just in case, but cb needs to be called even in that case too.
