Enter on an album card fetched the album's tracks over the IPC and ran the whole split state machine (splitMode true, splitIndex measured against the real container), then render() drew the single grid because it never consulted splitMode; connectedCallback referenced renderSplitGrid only to satisfy noUnusedLocals. perf.p2 files this as dead code — it is the only route from the albums grid to track-details, since a plain click navigates to the catalog page instead. Two things it needed that the audit does not mention. The grid could not scroll: .grid-scroll-container is the markup artists-view and genres-view use, and cover-grid had the class with no rule for it, so 186984px of albums sat in a 772px box at 5000 albums, unreachable by wheel, keyboard or scrollbar — and that is the element scroll-manager saves and restores, so its scrollTop was permanently 0. And the shared context menu was labelled 'Album actions' unconditionally, which nothing could observe while a track menu was unreachable. Both halves of the split grid carry the listbox semantics the single grid gained in the ARIA pass.

Discover and clean up (powered by MusicBrainz)
