【报Bug】editor富文本编辑器组件在ios端输入文字并插入图片后执行clear的时候，第二次输入的时候出现输入换行问题

示例代码：

<template>
<view class="container">
<editor id="editor" class="ql-container" :placeholder="placeholder" @ready="onEditorReady" @input="listenInput"></editor>
<button type="default" @touchstart.stop.prevent="insert">插入图片</button>
<button type="warn" @touchstart.stop.prevent="clear">清空</button>
</view>
</template>

<script>

export default {  

    data() {  
        return {  
            placeholder: '开始输入...'  
        }  
    },  
    methods: {  
        onEditorReady() {  
            uni.createSelectorQuery().select('#editor').context((res) => {  
                this.editorCtx = res.context  
            }).exec()  
        },  
        insert() {  
            this.editorCtx.insertImage({  
                src: 'https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1597926465183&di=7e80a34113fc7660436bb754aeb840f5&imgtype=0&src=http%3A%2F%2Fa3.att.hudong.com%2F14%2F75%2F01300000164186121366756803686.jpg',  
                width: '24px',  
                height: '24px',  
                extClass: 'emojiIcon'  
            })  
        },  
        clear() {  
            this.editorCtx.clear()  
        },  
        listenInput(e) {  
            console.log(e)  
        }  
    }  

}  

</script>

<style lang="scss">
.container {
padding: 10px;
}

    #editor {  
        width: 100%;  
        height: 300px;  
        background-color: #CCCCCC;  
    }  

    button {

            uni.createSelectorQuery().select('#editor').context((res) => {  
                this.editorCtx = res.context  
            }).exec()
