A location search that found nothing or failed now keeps its query, the open field and focus (text selected), and shows a persistent role=alert message under the search row instead of a toast. Typing, a new search or closing the emptied field clears it. HAL-727.
No markup carries a drag handle, so nothing called it: panel position
controls keep only collapsed state and the layout-reset notice.
