I started looking into this. My angle of attack would be:

1.) move m_elemStyle, m_mappedElementStyle, m_styleSheets, m_styleSheetCandidateNodes, and m_styleSelector from Document into TreeScope, i.e., having a style selector for each scope. m_pageUserSheet and m_pageGroupuserSheets remain on Document.

2.) change the code to call style selection on the TreeScope rather than the document.

3.) Adapt JS GC code as necessary

Now, before starting to actually implement this (and potentially wasting a lot of time), I wanted to confirm that this is a reasonable approach. Any remarks or suggestions?
