    Fix search handling when typing multiple searches in the search box
    
    In the current implementation of the search entry, when replacing a
    selected search term with another term, the first character of the
    replacement is prepended to the hint text rather than starting a new
    search. This fix makes sure that the focus is not lost when changing
    the selected search term.
