    fix: Never show conn details if panel's empty
    
    The connection panel could get stuck in the 'show connection details' mode if
    the panel's contents became empty while we were showing something. This
    wouldn't crash (like with the issue addressed in the previous fix), but the
    panel title would be wrong. This reverts the 'show details' flag if we don't
    have any contents.
