Unable to open library from assets panel

When I go to the assets panel and look at my connected libraries, I get an “open” button that appears when I hover over a library. For some reason, I thought I remember that clicking on the open button opened the library file in a new tab so you can view, inspect, duplicate to drafts, etc. as needed. However, it only opens the library preview (with the swap library button) in the same modal.

Is this a bug, or am I just incorrectly remembering how it functioned? If it never existed, is there a way to add that functionality?
