WKURLSchemeHandler does't run the CORS rule

[Jin]

When I setup a WKURLSchemeHandler with my custom Scheme, then send a XMLHTTPURLRequst .
Just like the following code:

var request = new XMLHttpRequest();
request.open('GET', 'https://www.apple.com/ac/globalnav/3/en_US/images/globalnav/search/image_small.svg', false);
request.send(null);


Webkit send the request immediately, but not send a Option request to www.apple.com which the CORS rule needed.


I hope WKURLSchemeHandler  should support CORS in the feature.

For Example:
Load request with "uc://www.google.com"
Then send a Sync XMLHttpRequest request 'https://www.apple.com/ac/globalnav/3/en_US/images/globalnav/search/image_small.svg'

The XMLHttpRequest just send to apple.com.

But if a send it with ASync mode , it will check the CORS rule
