Specifically, how does nesting details/summary tags relate to 5 MB of HTML, and how does that relate to breaking a lot of browsers?
Sounds like a great story, and I’d love to hear it!

Where each of those is a branch in the story. Even if both branches converge eventually, all possibilities need to be in each branch. And so on. The number of summary tags is n! where n is the number of possible decisions.
Thus you very, very quickly end up with a very large dom. Browsers aren’t really optimized to display hundreds of thousands of these tags, so they crashed.
