I just spent a lot of time trying to figure out why my collapsible headings didn't export to HTML correctly. Luckily I found it out: the heading only exports correctly if the heading is the only thing in the cell. A heading with introduction text mixed up everything in my notebook that came after it.
I think this should be made clear in the readme when it talks about exporting, or be fixed...
