fix(filters): a pick that hides More… keeps the focus, counts read alike, Plex facets say they failed

Picking in the year dialog the one year the chips hid took More… away with the dialog, and the
focus fell to <body>: it now goes to the picked year's chip. A count badge is compact in the UI
language everywhere (a chip read "17200" beside its cell's "17.2K"). While the Plex facets load
or fail, the sections they fill say so instead of vanishing as if the library had none.
