Comment on attachment 438152 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=438152&action=review DOM stuff looks good. > Source/WebCore/page/ResizeObservation.cpp:106 > +bool ResizeObservation::elementSizeChanged(BoxSizes& currentSize) const I would return either a pair or a bespoke struct here instead of using an out parameter. > Source/WebCore/page/ResizeObserverBoxOptions.idl:26 > +// https://wicg.github.io/ResizeObserver/ I would update this link to the more specific https://wicg.github.io/ResizeObserver/#enumdef-resizeobserverboxoptions or https://drafts.csswg.org/resize-observer/#enumdef-resizeobserverboxoptions. (I wish there were a way to point to a particular version, like based on the git sha), so that if the spec changes, we know which one our implementation was based on, but I don't think there is a way to do that. > Source/WebCore/page/ResizeObserverBoxOptions.idl:30 > + "content-box" I would put "device-pixel-content-box" commented out here with a bugzilla link to a bug about it. > Source/WebCore/page/ResizeObserverEntry.h:68 > + // The spec is designed to allow mulitple boxes for multicol scenarios, but for now these vectors only ever contain one entry. > + Vector<Ref<ResizeObserverSize>> m_borderBoxSizes; > + Vector<Ref<ResizeObserverSize>> m_contentBoxSizes; One day, we should really convert these types of immutable vectors that don't ever change size once constructed to use something more efficient like FixedVector (and we should fix FixedVector to not depend on RefCountedArray). > Source/WebCore/page/ResizeObserverOptions.idl:26 > +// https://wicg.github.io/ResizeObserver/ Again, I would use https://drafts.csswg.org/resize-observer/#dictdef-resizeobserveroptions > Source/WebCore/page/ResizeObserverSize.idl:26 > +// https://wicg.github.io/ResizeObserver/ Again, https://drafts.csswg.org/resize-observer/#resizeobserversize.
