Describe the bug

When the passage gets too long, the structure of the article can't display everything, but flash and disappear when browsing.

Expected behavior

The structure of the article can be scrolled or something to fit long passages.

Screenshots

I have a webpage on my github.io here so you can scroll over it:

Hi @glyh,

Sorry for sooo long response. I took a look and I observed that on the original CodeIT theme (the example site), the issue is not reproducible.

When I tried to use your minimalistic config, the issue appeared. I think there is a misconfiguration but I didn't get what is the specific configuration. I'll keep you in touch.

Never mind, after all it's open source. And thanks for your contribution! I'm going to look it up some time.
