The currentItem fixup done by BackForwardList::pushStateItem should be moved into HistoryController::pushState

The BackForwardList operates on the top-most HistoryItem node.  The HistoryController operates on the HistoryItem corresponding to a particular frame.

Note: the dereference of m_previousItem in HistoryController::pushState is protected by the null check of m_currentItem at the top of the function.  This is because createItemTree has the side-effect of assigning m_previousItem.

LOL, m_frame->loader()->history() is a roundabout way of writing "this"!

Yup, and I was so proud of myself for avoiding HistoryItem::targetItem() too ;-)
