你好，下面属性支持吗

get
set
deleteProperty
has
ownKeys

My expectation was that the polyfill would only be used if there is no proxy support in the browser.
Unfortunately this is not the case and a simple test in a Vue.js application, which unfortunately also has to support IE 11, immediately led to a bug in Firefox 76.
By the way, it does not work in IE 11 either...

import 'es6-proxy-polyfill'

export default {
	name: 'App',
	components: {},
	data: function() {
		return {
			myprop: ''
		};
	},
	created() {
		const test = new Proxy({}, {
			set: (target, prop, value) => {
				console.log(target, prop, value)
				target[prop] = value
				return true
			}
		})
		test.name = 'Hans'
		console.log(test.name)
	}
}

IE 11
"TypeError: Trap 'set' returned false for property 'length'

在ie11中使用mobx6,可复现问题
