           Summary: Safari15.4 can be CRASH when exec putImageData when
                    imageData more than 512kb on window.open page.
           Product: WebKit
           Version: Safari 15

I simplify the way to crash on safari15.4.

Step1: window.open a page;
Step2:  CanvasRenderingContext2D.putImageData(imageData, 0, 0), than CRASH!

tip: imageData size more than 524 * 1000.
