[New Multicolumn] Writing mode and direction of flow thread can mismatch enclosing paginated RenderView

• Component: Layout and Rendering
• Status: RESOLVED FIXED

[Dave Hyatt]

When a document propagates a writing mode change or direction change up to the view, we don't properly update the writing-mode and direction of column sets or flow thread if the view is paginated.

Slightly risky that someone will move rootRenderer outside the isBodyRenderer blocks below, but hopefully no one will be that careless ($10 that it will be me in 4 years time).
