Parsing srcset=', 2x'

[marcoscaceres]

I'm not sure, but it appears that parsing srcset=', 2x' should return the url ","?

[borismus]

What is the expected behavior for this case?

[marcoscaceres]

That the URL would resolve to "http://example.com/,"

Per the current spec the comma is skipped and 2x is the URL.
