typo() on a textframe applies properties in the wrong scope

[trych]

Putting this here quickly, need to investigate this closer later:

When typo() is used on a text frame to change a property of the contained text, apparently the property gets applied on a per-paragraph-basis. That means in cases where the paragraph spans several text frames, not only the text within the given text frame gets affected, but also the text within the same paragraph in the next text frames.
