Fixes #24064

Broken scroll on submenus

💡 Background and solution

Seems the position: absolute; was breaking the scroll. I don't see it break any of the other examples, but I'm new here so ¯\(ツ)/¯ could be wrong. . . Also removed top, left, right, and bottom properties as they will no longer do any good.
