What happened?

When clicking on a product's screenshot, the full image usually opens open in a full screen modal that is centered on the viewport no matter where you're at on the page. However in Zen, when opening a screenshot it appears to open in the middle of the page, causing the screenshot to appear off screen if you're at the top, or at the top if you're at the bottom.

There is also a problem with embeds, which I believe are iframes, they render as all black.

this is what I get on Zen

and this is the intended behaviour

And yes it is an iframe, here is what itch.io gives for embeds

<iframe frameborder="0" src="https://itch.io/embed/2874314" width="552" height="167"><a href="https://ltngames.itch.io/fenixengine-video-volume-x">Video Volume X for RPG Maker by LTN Games</a></iframe>

Reproducible?
