Description Said Abou-Hallawa 2023-05-25 15:53:42 PDT 
264433@main made RenderBoxModelObject::decodingModeForImageDraw() call RenderElement::imageVisibleInViewport() for all images including the small ones which do not require async image decoding unless the attribute decoding="async" is specified.

This regressed the score of the MotionMark Leaves sub-test by almost 2.5%.
