Reviewed by Tim Horton.

For each layout that comes in until the user scrolls we need to reset
the scroll to keep the fragment in the middle of the page.
Otherwise, more content can come in the scroll the fragment off the
page, which can be very confusing to the user.

* Source/WebCore/page/FrameView.cpp:
(WebCore::FrameView::reset):
(WebCore::FrameView::scrollToFragment):
(WebCore::FrameView::maintainScrollPositionAtRange):
(WebCore::FrameView::textFragmentIndicatorTimerFired):
(WebCore::FrameView::cancelScheduledTextFragmentIndicatorTimer):
(WebCore::FrameView::scrollToRange):
(WebCore::FrameView::performPostLayoutTasks):
* Source/WebCore/page/FrameView.h:
