Why are the covers so small in Tags

I was browsing Tags and wondered why are the album covers so small?
I read something in the past, could be it is representing a track?
Well, it makes no sense to me, it looks awful.
Please consider full album art.

Interesting. My display is just like the album browser display. See below.

Those are full albums I guess, it is the way Roon shows the difference between Albums & Tracks, can’t find where I read it.
But the difference is als in text shown so there is no need.
