        <pre>We're seeing this same bug with soundslice.com, which offers an embedded iframe sheet-music viewer that optionally does referrer checking. Referrer checking is broken in iOS 9.3, which means our iframes are broken.

This bug also affects Vimeo Pro video embeds, which apparently do the same whitelist referrer checking.</pre>
