It is fixable but as I thought about it some more I reached the conclusion that fixing this was the wrong thing to do. By leaving the behaviour as it is - and documenting it more clearly - users retain the option to select the behaviour that best suits there needs. I have, therefore, updated the docs for 9.0.0.M11, 8.5.6 and 8.0.38 to explain the differences in behaviour.
