interop: blob with empty content type is not converted to text/xml #357

Open dlrobertson opened 1 year ago

dlrobertson commented 1 year ago

According to https://xhr.spec.whatwg.org/#response-mime-type:

If mimeType is failure, then set mimeType to text/xml.

Note: The content-type of the blob is set to "" (an invalid mime type) when the input type is not set or is invalid.

Test Firefox Chrome Safari
no content type text/xml null ""
bad content type text/xml null ""

I'm not entirely sure how to interpret this. Are you simultaneously pointing out that it's inconsistent with blobs and that browsers are not aligned on this?

dlrobertson commented 1 year ago

Ah, sorry just that browsers are not aligned on this.

I see, I kinda suspect this already has test coverage so unless that's not the case or someone wants to make a change to the spec this might be a good fit for the Interop effort?
