Is this too big of a hammer for this issue?

I guess it's just a performance optimization, so ok.

We can think of this as: when printing anonymous block containing a link with
continuations, besides the visual overflow of the block itself, we also need to
include the visual overflow of the continuations (by
addElementVisualOverflowRects).

 
     if (m_layoutBlock.hasOverflowModel() && m_layoutBlock.usesCompositedScrolling()) {
         overflowRect.unite(m_layoutBlock.layoutOverflowRect());
