I think toc("h2,h3") would make more sense here, to exclude the title from the TOC. 
Or even better, let the default be selector = "h2,h3".

Unfortunately, in Safari (at least v. 14) `h.scrollIntoView()` does not work for elements inside an iframe, as with Observable notebook content. I wonder if there is a reasonable workaround.

The links generated only work in the opened notebook.  If the link is used to open in other tab then the links don't work.

Example:  
https://observablehq.com/@ambassadors/awesome-notebooks#data-management  
doesn't work when opened in new tab or shared outside the notebook. 
The reference for those cases is https://observablehq.com/@ambassadors/awesome-notebooks#cell-386
