So that we can get the correct client offset value and store other metrics
there and reuse them when the top browser window moves.
The client offset, browser window title bar and window decorated frame width,
is necessary to get element positions in OOP iframes in screen coordinates
for drag-and-drop etc.
This change also fixes event.screen{X,Y}. A mochitest in this commit fails
without this change with enabling fission at least on Linux. Note that in the
mochitest we have to use nsIDOMWindowUtils.synthesizeNativeMouseClick instead
of nsIDOMWindowUtils.sendMouseEvent since sendMouseEvent doesn't work in fission
world (bug 1528935).
