Are you referring to "If there is no previous document, this attribute must return the same value as fetchStart"?
Yes.
As ppi@ noted in his doc: "In fact, however, the HTML spec requires every new browsing context to load the about:blank document at initialization, therefore there is always a previous document and this particular condition never applies." [1]
That note is incorrect, because this condition applies to the about:blank document that's loaded at initialization! That's the whole point. We've covered all this ground before, on this mailing list...
How is about:blank special, won't it trigger the same navigation algorithm? [2]
_Initial_ about:blank won't. Other about:blank will. -Boris
