Yes, much better, a follow-up on #29474. I think that they should be no scroll at all. Personally, I would revert #29141 and close #29119 as "won't fix".

@oliviertassinari I agree with you. No scrolling would be better.

I'm moving in circles with this one a bit. When we first implemented it, I thought that no scroll was better, especially because the point of this section was more to act as an illustration—the components being interactive were meant to be a cool sort of "easter egg".

Then, when proposed to add the scroll bar due to wanting to interact with the components, that seemed to make sense, as depending on the browser window size, some of them get cut up.

Now, I'm back to the initial place where I'd go without scrollbars like both of you are suggesting, I do think it's meant to serve more as illustration than anything else.

Though if we move forward with this approach, we'd need to remove it from the other pages as well:

• /core
• /x

Looks great 👍
