Esri Map not loaded when its out of browser view port

[YangJin]

Hi guys, 

I’ve observed that the Esri Map only loads when it enters the browser’s viewport (I'm using Chrome), seems Esri has lazy loading mechanism for performance optimization. Is this behavior intentional, and if so, is there a way to force the map to load even when it's outside the viewport?

Thanks,

Yang
