Resize Current Caret While Autoscaling

This commit contributes to autoscaling the Caret which was last managed
by the OS (hence the current caret) while autoscaling since there can
only be one Caret visibile at a time. Also, the changes make sure that
we do not change the visibility state of the Caret while autoscaling.
