On mobile, the AI Concierge chat can open on its own after a search, showing a stray slash character.
Why this happens. In versions before HomeRunner Toolkit v3.87.1, search URLs carry an empty ask parameter. When a browser or test environment appends a stray trailing slash to the URL, that slash opens the Concierge chat on mobile, and the Concierge opens over the junk value.
What to do. This is corrected in HomeRunner Toolkit v3.87.1. From that version, search URLs no longer carry empty ask parameters, which prevents this behavior.
