trackProgress is musicBarPanel own first child inside a 3-column grid
(track/transport/side), with no grid-column of its own - auto-placement
dropped it into column 1 of row 1 like any other item, squeezing it to
that columns width and wrapping musicBarPanelSide onto a second row
underneath instead of spanning the full bar with everything else in
one row below, as its own comment already said it should. Fixed with
grid-column: 1 / -1, which pushes every sibling after it into row 2
across the full width with no changes needed to any of them.
