YouTube embedding broken?

From a [private report](https://anki.tenderapp.com/discussions/private/39508-youtube-embedding-error-on-ankimobile):

> The problem I ran into with AnkiMobile is when my card creates a YouTube player using the YouTube Iframe API, an error occurs: "Error 153 / Video player configuration error". The same code works on Anki desktop and AnkiWeb without any issue.
>
> I found the following discussion in the public forum, but it was closed without a resolution.

> I wonder if you concur with the proposed cause of the issue, that is, the http header "referrer" was not set to what YouTube required. If so, is it in the plan to fix it?

> Being able to embed a video in the card and control the play is quite a useful feature for the shadowing practice.
