closes#3855
unlike #3854, this implementation uses a generic details html tag and a bit of tailwind magic...
---
## Maintainers Note
- previously tailwind classes of the form `[-a-zA-Z:0-9_.]` was disabled, however they were enabled since they were required for the `group-open:` classes

1. the results are unfloded/open by default
2. the chevron points down when open and right when closed
