Current

SuperCall : super Arguments

1. Let newTarget be GetNewTarget().
2. Assert: Type(newTarget) is Object.
3. Let func be ? GetSuperConstructor().
4. Let argList be ? ArgumentListEvaluation of Arguments.
5. Let result be ? Construct(func, argList, newTarget).

The WeakRef Constructor
https://tc39.github.io/proposal-weakrefs/#sec-weak-ref-constructor

- [ ] is the initial value of the WeakRef property of the global object.
- [ ] is designed to be subclassable. It may be used as the value in an extends clause of a class definition. Subclass constructors that intend to inherit the specified WeakRef behaviour must include a super call to the WeakRef constructor to create and initialize the subclass instance with the internal state necessary to support the  WeakRef.prototype built-in methods.

WeakRef ( target )
https://tc39.github.io/proposal-weakrefs/#sec-weak-ref-target

1. [ ] If NewTarget is undefined, throw a TypeError exception.

The "search" event

whatwg/html#667

Some browsers feature non-standard attributes incremental and onsearch for the <input type=search> elements. This also implies the search event being fired.

• Specified? no
• Proposed? no.
  • This link shows a refusal to propose the idea and reasons for it.
• Is it a good idea? no.
• The refusal to proposal the idea bases on the fact it's already redundant with the oninput and onsubmit event handlers
