"""Issue #2919 — openPanel must reset _searchQuery so a reopened Notes panel
doesn't keep filtering by a stale query (the rebuilt search box renders empty).

notes.js is a browser ES module with a heavy import chain (can't node-import in
isolation), so — per the repo's DOM-coupled-guard convention — this asserts the
reset is present in openPanel, beside the existing _editingId reset.
