Not sure why my last thread was deleted, I didn't get a reason. Is this not the forum to report issues?
I'm planning on working on an EPUB with a lot of math in it, so I checked if the test epub file renders properly first. It renders as intended in the Readium preview, but the Preview pane only renders it as a single line. I'm guessing the code is changed a bit when it's passed to the preview pane, or MathML just adds a lot of stuff that makes it easy to mess up. This isn't that big of a deal, just wondering if there's a fix for it before I start working on it.
Here's a screenshot.
