Mouse can lose button up events if outside bounds of canvas about engine HOT 3 CLOSED

With change 7dcc7dc we have possibility to catch any scenarios outside of canvas.
We need to decide wether moving mouse outside of canvas will finish mouse event, triggering isPressed right at the edge of canvas element where mouse left canvas. Or should we allow mouse move outside of canvas clamping mouse coords within canvas element? And handling all mouseup events as suppose to, even if they are outside of canvas?
