Re: [w3c/clipboard-apis] Should the constructor of ClipboardItem accept record<DOMString, ClipboardItemDataType>? (#102)

First of all, WebIDL does not support a method accepting either a promise type or a non-promise type (i.e. "Promise types [...] are not distinguishable with any other type."). But in this case that doesn't matter either. The way WebIDL converts an ecmascript value to a Promise type implicitly wraps any non-promise type in a promise anyway, so by accepting ClipboardItemData, the method already accepts ClipboardItemDataType as well.
