Hi Team,

While going through Blink's commit, I came across another failing test case:

Test Case (from Chrome bug): https://jsfiddle.net/jhmsh/

^ Fails in Safari / WebKit ToT only. While Chrome Canary 121 and Firefox Nightly 121 are same.

Blink Commit: https://chromium.googlesource.com/chromium/blink/+/436fb328f44f79caa4c8a8f5804ca305467f026b

Just raising so we can fix it.

Thanks!

Something along the lines - maybe?:

destinationRect.moveBy(-result.absoluteImageRect().location());

filterContext.drawImageBuffer(*inputImage2, destinationRect, FloatRect(source2Rect));

filterContext.drawImageBuffer(*inputImage, destinationRect, FloatRect(sourceRect), { CompositeOperator::SourceIn });
