Description of the problem

While visiting any user profile, e.g., mine is https://codesandbox.io/u/ditectrev, there are no CodeSandboxes despite the fact they're all public, in a folder. I was in touch with James A. from Support, he said it's intentional, but I'm curious if others are feeling the same as me it should be there, very basic feature. If I look at CodePen, its content inside folders, so-called "collections", are visible https://codepen.io/BlogFire/collections/ & https://codepen.io/Mohammed-Hamza_Pakistan/collections/ & ...

How has this issue affected you? What are you trying to accomplish?

It's not showing my CodeSandboxes.

To Reproduce

Go to any user profile that has public folders, for example, https://codesandbox.io/u/ditectrev

Your Environment

Screenshots

Start by reproducing the behavior on a user profile with public folders, such as the linked profile, and inspect the profile UI and folder listing entry points. Done means public sandboxes contained in folders are visible from the owner's profile, with existing profile behavior preserved.
