Description Andrei Bucur 2014-03-21 05:39:42 PDT
mapLocalToContainer should be able to select the correct region when walking the ancestor path of a renderer inside a flow thread. The problem is that rectangles are shifted from their layout positions through transforms / relative positioning. Correct region information can't be collected using only geometrical values.

Because of this limitation, getClientRects() will return invalid results in some cases (with content overflowing the region).
