If you're talking about the Living Specification [0] edited by Simon
Pieters, he tells me that this is covered in the HTML spec [1]:

| When an img element ... does not represent an image, but the element
| already has intrinsic dimensions (e.g. from the dimension attributes or
| CSS rules), and either the user agent has reason to believe that the
| image will become available and be rendered in due course or the
| Document is in quirks mode, the element is expected to be treated as a
| replaced element whose content is the text that the element represents,
| if any, optionally alongside an icon indicating that the image is being
| obtained.
