Hi Team,

While going through Blink's commit, it seems that Webkit wait for image to be loaded rather than loading it progressively.

Failing Test Case - https://jsfiddle.net/6y4zjb17/

Safari 16.1 will take ages to load image while Chrome will load it progressively.

Blink Commit - https://src.chromium.org/viewvc/blink?view=revision&revision=198593

Webkit GitHub Source - https://github.com/WebKit/WebKit/blob/bf6ec0b71883ada1ee6d8d0c66a8ea7e421c5e27/Source/WebCore/rendering/RenderLayerBacking.cpp#LL3109

Just wanted to raise this bug so this can be fixed.

Thanks!
