fix(playlists): the list's name keeps its room on a narrow window

Below xl Unsynced is its dot; on a phone the cover is gone, Play all is its
glyph, the band's count is its number and the undo pair stays out. The name was
0 px wide in Hungarian at 768 and on any phone, and a tick moved the list there.

   Below `xl` the band's buttons are glyphs named in their tooltips, and a filter's hidden count is "+N" with
   its sentence in the tooltip. The row the band replaces keeps its height, invisible, so a tick moves no row.
