* Source/WebCore/editing/cocoa/WebContentReaderCocoa.mm:
(WebCore::replaceRichContentWithAttachments):

Create <attachment>s for <source> if they represent inline images.

* Source/WebCore/html/HTMLSourceElement.cpp:
(WebCore::HTMLSourceElement::attributeContainsURL const):

Mark `srcset` as a URL containing attribute, so that subresource replacement
can be performed. This matches existing logic in `HTMLImageElement`.

* Source/WebCore/html/HTMLSourceElement.h:
