#401 introduced player.current?.id reads into TrackRow.svelte and
PlaylistTrackRow.svelte, breaking 26 test cases across 6 files whose
existing vi.mock('$lib/player/store.svelte', ...) blocks only stubbed
the functions used by the original components.
Added player: { current: undefined } to each affected mock — keeps
the existing function spies and lets the new isCurrent derivation
read a defined (false-y) player.current without blowing up.
Only updated the 6 files that failed; 16 other player-store mocks
exist across the suite but their tests don't render Track/Playlist
rows so the derivation never fires. Future tests that render those
rows will need the same stub (visible at the failure point with a
clear error message).
