tn: is this something you can take a look at? It's not really my area of expertise...
Yes, I'll look into it.
The iframes get a small height value when the bug appears. So I'm guessing the code twitter is using to autosize the iframes is getting confused or wrong values or something.
This looks fixed to me now. Can you reproduce anymore?
