Caolán McNamara c36fff84af Resolves: tdf#144376 focus into protected ScTextWnd shouldn't be possible
the expectations are that this isn't possible and if it happens then
under windows there is a QueryCharPosition which will trigger the
deletion of the ScTextWnd EditView due to that expectation before it is
then unconditionally dereferenced
