Thank you for catching this Michelle! Gijs probably covered this in his summary change, but this issue seems to predate the zoom indicator. I've added an attachment showing that the page information gets jumbled at large zoom levels as well in the release version of Firefox.

I can reproduce the same result on Safari and Chrome. I think the page doesn't consider such large zoom scale. The developers of the page may need to change some CSS properties if they want to fix it.
Michelle, can you help me confirm it?

What Ethan said. I don't think this is a bug in Firefox, the page is just not designed to work well at such high zoom levels.
