fix: jump to message in search fails for messages high up in timeline (#6714)

closeSearch() added onSearchValueChanged("") in d30dde5 (content filter
feature) which triggers async apiFindMessages — this clears the items
that openChat just loaded around the target and replaces them with
initial messages. Skip the reload when openAroundItemId is already set.
