------------------------------------------
Drools was deprecated, I'll thus resolve this as WONTFIX.

> Some debugging revealed that StyledTextRenderer's internal data structures assume a different number of lines present than what content.getLineCount() returns in calculateClientArea(); these two values are usually kept in sync with the use of TextChangeListeners. I think that because of TransformedDocument's lazy update mechanism, new state can be returned to the renderer without firing a corresponding text change event first.
