【报Bug】使用 editor 中的 getSelectorText 无法获取到选中的内容

示例代码：

<template>  
    <view class="content">  
        <!-- <image class="logo" src="/static/logo.png"></image> -->  
        <view class="text-area">  
            <!-- <text class="title">{{title}}</text> -->  
                        <!-- 这里用focus也不行 -->  
            <editor id="editor" @ready="onEditorReady" @tap="onEditorFocus" placeholder="再次输入"></editor>  
        </view>  
    </view>  
</template>  

<script>  
    export default {  
        data() {  
            return {  
                // title: 'Hello',  
                editorCtx: null  
            }  
        },  
        onLoad() {  

        },  
        methods: {  
            onEditorReady(){  
                let that = this  
                    this.$nextTick(()=>{  
                        uni.createSelectorQuery().in(this).select('#editor').context((res) => {  
                            console.log(res.context);  
                            that.editorCtx = res.context  
                        }).exec()  
                        setTimeout(()=>{  
                            this.editorCtx.setContents({  
                                html: ""  
                            })  
                        },1000)  
                    })  
            },  
            onEditorFocus(){  
                this.onselectText()  
            },  
            onselectText(){  
                let that = this  
                this.editorCtx.getSelectionText({  
                    success(res){  
                        console.log(res,"选中的内容");  
                        that.selectText = res.text  
                    },  
                    fail(fail){  
                        console.log(fail)  
                    }  
                })  

            },  
        }  
    }  
</script>  

操作步骤：

<template>  
    <view class="content">  
        <!-- <image class="logo" src="/static/logo.png"></image> -->  
        <view class="text-area">  
            <!-- <text class="title">{{title}}</text> -->  
                         <!-- 这里用focus也不行 -->  
            <editor id="editor" @ready="onEditorReady" @tap="onEditorFocus" placeholder="再次输入"></editor>  
        </view>  
    </view>  
</template>  

<script>  
    export default {  
        data() {  
            return {  
                // title: 'Hello',  
                editorCtx: null  
            }  
        },  
        onLoad() {  

        },  
        methods: {  
            onEditorReady(){  
                let that = this  
                    this.$nextTick(()=>{  
                        uni.createSelectorQuery().in(this).select('#editor').context((res) => {  
                            console.log(res.context);  
                            that.editorCtx = res.context  
                        }).exec()  
                        setTimeout(()=>{  
                            this.editorCtx.setContents({  
                                html: ""  
                            })  
                        },1000)  
                    })  
            },  
            onEditorFocus(){  
                this.onselectText()  
            },  
            onselectText(){  
                let that = this  
                this.editorCtx.getSelectionText({  
                    success(res){  
                        console.log(res,"选中的内容");  
                        that.selectText = res.text  
                    },  
                    fail(fail){  
                        console.log(fail)  
                    }  
                })  

            },  
        }  
    }  
</script>  

预期结果：

{  
   "errMsg": "ok",  
   "text":"选择"  
}

实际结果：

{  
   "errMsg": "ok",  
   "text":""  
}
