External XML Styles overritten by default styles

[jordanwarner]

In #3345 the default styles are added in even when you have external xml styles. If you have styled any of those default items (Title, Heading1, Heading2, etc.) in your external xml styles they are overwritten by the default style.

A (truncated) version of the the generated xml is below, with the default 'Title' style at the top overwritting the custom 'Title' style at the bottom.
