Fix inline tooltip position is wrong

The PopupWindow will show up above the anchor with the real rectangle.
If the anchor is doing an animation, it will get a temporary top of the
anchor because the rectangle is conisince changed by the animation. So
attach tooltip after a while for waiting the animation is done.
And when the tooltip overrides the inline suggestion, clicking the
suggestion won't work. Force the y offset above or below the anchor to
fix the problem.
