PlayCanvas demo not scaling to requested size in Preview

The requested size of canvas is 300x300 but it is bigger in Preview: https://plnkr.co/edit/nEchdgd1UQYDClR1?preview

Hey, if I remember correctly, there's some subtle trickery going on in the preview. It's an iframe nested within another controller iframe. I believe that the nested iframe gets resized to fit the container given that the space allocated to that controlling iframe is unknown a priori.

The following code in your plunk is probably responsible:

// Ensure canvas is resized when window changes size
window.addEventListener("resize", () => app.resizeCanvas());

I commented it out and the issue was fixed. Thank you very much!

// Ensure canvas is resized when window changes size
// window.addEventListener("resize", () => app.resizeCanvas());
