    math-preferences: Fix setting the switch state
    
    The callback should return true to stop propagation and false otherwise.
    Here we don't return anything, which is wrong and make the propagation
    stop, which isn't what we want. This makes the callbacks correctly
    propagate the set-state signal so the switchs can acquire the checked
    state.
