This is weird, I'll try working on a fix. It should display correctly in Chrome, if you have that. For now, I put up a downloadable demo, so you can grab that instead! :)
I'm using Chrome, on MacOS if that matters, and I'm seeing the same thing. Speaking of a demo, could you upload a demo for MacOS too?
And I'm using Firefox, on Arch Linux.I too see the same thing. And this is in the browser.
