Sorry you spent that effort to powerwash and go back and forth between channels. As you found, the bug is with the latest builds of Chrome Browser, regardless of it being Windows or Mac or Chrome OS X.
I heard back from Obihai that they're aware of the issue and they're looking into fixing it.
So, again: until this is fixed, use another browser (or another computer if you're a Chrome OS user) if possible, or you can use the direct URLs to the frames, linked above.
