FloatingToolbar: Offset visible rect by the rootview's offset

windowSoftInputMode="adjustPan" config causes the root view to be
offset if necessary when the soft keyboard is shown to keep the text
selection visible. Account for this offset when calculating the
global visible rect of the textview in relation to the screen.
