The sliding active indicator positioned itself via Repeater.itemAt(), which
returns null mid-rebuild; the fallback then stranded it at the top (looked
like workspace 1 was active while the font correctly showed another). Cells
are uniform, so compute the indicator's y arithmetically from the index
instead. Also make monitorWsData's sort deterministic: numbered workspaces
ascending, then named ones (e.g. joplin) alphabetically — parseInt alone
yields NaN and an unstable order for named workspaces.
