Comment on attachment 456817 [details] Handle selection View in context: https://bugs.webkit.org/attachment.cgi?id=456817&action=review > Source/WebCore/rendering/style/RenderStyle.h:543 > + bool containsSize() const { return effectiveContainment().contains(Containment::Size) || skipsContents(); } Maybe we can also move `skipsContents()` inside `effectiveContainment()`? Not sure why `containsLayout`, `containsStyle`, and `containsPaint` do not check `skipsContents()` like `containsSize`?

Not sure why `containsLayout`, `containsStyle`, and `containsPaint` do not check `skipsContents()` like `containsSize`? See https://drafts.csswg.org/css-contain/#valdef-content-visibility-auto: "Turns on layout containment, style containment, and paint containment for the element." For c-v: hidden all containment is enabled. But actually, I am not sure in our patches c-v: hidden always enables size containment unconditionally....
