In Workbench 2, if you follow the link for a portable data hash (e.g., in the workflow input list), that visits /collections/PDH, which quickly redirects you to /collections/UUID.

On this collection page, if you press your browser's back button, you go back to /collections/PDH, which just re-redirects you to /collections/UUID again.

The end result is you can't use the back button to go back to the page where you opened the collection from. I think this should be possible.
