"Move between lists" and "Sort a listbox" not working on initial page with all examples

[patrickhlauke]

When going to https://salesforce-ux.github.io/dnd-a11y-patterns/ all examples/cases are shown in a single page. When on this page, the "Move between lists" and "Sort a listbox" examples do not work using the mouse.

However, they do work as they should once using the navigation and going to the specific examples (https://salesforce-ux.github.io/dnd-a11y-patterns/#/bucket?_k=xmy8qs and https://salesforce-ux.github.io/dnd-a11y-patterns/#/sortB?_k=irozk4)
