Synopsis can't be hidden in MS Edge Browser

[gbaz]

Not my issue, haven't reprod. Just passing this report from @ghost on

System: MS Windows 10
Internet browser: MS Edge
Haskell Platform: 8.6.3
"Synopsis" button don't work. "Synopsis" is open by default eg for Data.List and covers the most of page. The problem is from an earlier version, but I do not remember which one. The same is for example on https://downloads.haskell.org/~ghc/latest/docs/html/libraries/base-4.12.0.0/Data-List.html

Whoever wrote that report is right. I just tried this on a win10 VM and the synopsis is open by default. Even worse: I can't get it to go away at all!

No Haskell lover uses Edge though!

It would appear that Edge doesn't support summary/details tags, but that might also be changing (see MDN browser compat graphs for summary and details).

Does there exist a cross-platform solution for summary/details-like behaviour (that doesn't pull in a boatload of JS with it)? I'm out of my depth.
