Now using eq_ignore_case on WASM mimetype, per #25317
I have no idea how this would be tested.

let document.createElement[NS] accept a string for options
The string actually does nothing, but spec and WPT don't want it to do anything. https://dom.spec.whatwg.org/#dom-document-createelement only cares about the options value when it's a dictionary, and the WPT test on the string case is just that it isn't throwing an exception.

apply is: to Document.createElement even when name isn't registered yet
The "is" option to Document.createElement should be respected even when the name hasn't been registered yet, in which case the name gets looked up again at the time the element should be upgraded. This change does that.
I'm now seeing a few test timeouts that aren't in the metadata, but I suspect they're slowness on my local configuration and not actual breakage.

Remove obsolete HasInstance behavior per heycam/webidl #356
This turns one WPT test from fail to pass and it leaves Servo with a little less platform object special-case code to worry about.
