In https://commits.webkit.org/253809@main, both RenderLayer::recursiveUpdateLayerPositions and RenderLayer::flagsForUpdateLayerPositions check RenderElement::canContainFixedPositionObjects() to decide whether to add the SeenFixedContainingBlockLayer flag, but this function always render true for RenderView. RenderLayer::recursiveUpdateLayerPositions excludes that case while RenderLayer::flagsForUpdateLayerPositions does not, they should be made consistent.
