I agree with this change since this will make WebKit compliant with the specs and the other browsers. I did a basic testing and I found out WebKt does not apply any linking style when drawing an SVG to a canvas (see attached test case). But I think the WebKit security team needs to sign off on this as well. Brent, do you agree with this change?
