Find a library item. Edit its metadata. Go to tags, for instance. Scroll down to collections and begin typing. Plex will pop up an auto-complete dropdown for your list of collections. Unfortunately, because collections is the last metadata field inside the scrolling box, the autocomplete field will mostly be hidden beneath the bottom of the box. Depending on your resolution you might get one line of the autocomplete box. You can scroll down with the scroll wheel since the internal box has now been stretched, but personally I find this a little annoying because typically the mouse focus is on the autocomplete box itself, meaning scrolling requires moving the mouse outside the box. I’m getting the feeling I’m not doing great justice explaining this, but I think in general if you spend a few minutes playing around with this you’ll see it feels pretty crummy.
I guess technically this isn’t a bug, so much as it is a UI/UX workflow that feels terrible, but I tend to be of the opinion that UX issues are indeed bugs unless specifically intended.
