This gets translated to a < video style=“position:absolute; top:0; left:0; width:100%; height:100%” controls="" autoplay="">< /video>
I assume this is not intended, because it can be really annoying. Either the autoplay attribute should be removed, or the “muted” attribute added.
Edit: It doesn’t seem to work at all here. Apparently it just turns into a blank iframe. You should be able to see it here: Instagram autoplay with sound - What the Daily WTF?
