Both the ScrollingCoordinator's m_stateNodeMap and ScrollingTree's m_nodeMap get larger and larger as you navigate between pages.

This patch depends on the patch in bug 109361, so will probably fail EWS.
Comment 3 Simon Fraser (smfr) 2013-02-09 13:03:28 PST
The changelog should say that this isn't testable, because we only dump the state node tree (which is OK), not the hash map. The scrolling node tree does accumulate extra children, but we don't dump that.
