If I have an nested empty iframe (src is set to about:blank), tweets I try to load using the oEmbed code no longer show up.
This was working fine on January 10 but broke on January 11.
<iframe src="https://actual-link-to-site"> <iframe src="about:blank"> // oembed code </iframe> </iframe>
The code that fails is in the widgets.js that is loaded from the tag provided in the oEmbed.
The following check is done:
"http:" !== l.protocol && "https:" !== l.protocol
the object l here is my inner iframe and the protocol is set to about:blank, so this will fail.
I would expect it to refer to the parent iframe which has the actual src property set.
