Fix the issue of showing active mark for a frame in a tween - Does not show active frame if user set an active frame in a tween and move the to other frame. - Frameline only redraw active mark of the current active frame is same as one of new hover and last hover frame. - It is fixed by detecting if the crruent active frame is in the same frame as one of new hover and last hover frame.
