I’m going to make a weird counterintuitive suggestion here because I’ve had this happen to me a long time before and it took forever to fix, I dont remember exactly what caused the problem but anyway… here’s hoping it will solve this for you or prod you along.
Try defining the height for that specific <a> element in the list, or make the font-size larger. Does the logo show when you do that?
I just checked; if you increase the font size via the browser you will see the full logo. So I’m guessing the text/link is forcing a different height there. Just apply the height to the <a> element.
Well, I dont know, but you’ve perked my interest. I spent a few minutes googling it and came across this:

I don’t know if this will help you at all, I haven’t looked into it deeply yet. I just scanned the features, maybe it’ll give you somewhere to start?
