Here’s an example of where this behavior is problematic:
https://meta.discourse.org/tos
If you’re tempted to click any of the TOC links and then return to your starting point via browser history, you can’t.
Why provide a TOC in the first place?
For those sites that would like to support the standard browser navigation, any suggestions?
I’m looking into monkeypatching the scroll-to-element behavior that I suspect is behind this but I’m starting with literally no knowledge of the codebase 
I’ll get there eventually but if someone has some pointers, I appreciate the help!
