typescript vue Throttle ResizeObserver this指向错误？

Question

我在用Typescript重构vue组件时，loash的Throttle方法this的指向错误，

<template lang="pug">
    .vue-waterfall-ex-container( ref="outerEl" )
</template>

<script lang="ts">
    import { Component, Vue, Prop, Watch, Ref, Emit } from "vue-property-decorator"
    import { Throttle } from "lodash-decorators"

    @Ref("outerEl") readonly outerEl: HTMLDivElement

    @Component
    export default class VueWaterfallEx extends Vue {
        private mounted(): void {
            this.resizeObserver = new ResizeObserver(this.onContainerResized)
            this.resizeObserver.observe(this.outerEl)
        }
        
        @Throttle(250)
        private onContainerResized(): void {
            console.log(this) // 打印 ResizeObserver {}， 这里的this指向错误
        }
    }
</script>

请问，这应该怎么解决呢？

函数都写到class外了...
