Example URL:
www.bannerhost.hu/test/Surf_640x360_SIZMEK

What is the expected behavior?
All the <canvas> elements should display properly

What went wrong?
The big <canvas> elements are disappearing.

Does it occur on multiple sites: N/A

Is it a problem with a plugin? No 

Did this work before? N/A 

Does this work in other browsers? Yes 

Chrome version: 51.0.2704.84  Channel: stable
OS Version: 6.1 (Windows 7, Windows Server 2008 R2)

I suppose it is happening when the canvas element's area is bigger than 65536 pixels.
