微信小程序map，使用自定义callout， cover-view点击事件不生效，使用bindtap和catchtap都不行，真机和模拟器都不行，请问是为什么？

<view class="container">
    <map id="map" longitude="{{longitude}}" latitude="{{latitude}}" scale="12" class="map" markers="{{clubs}}" zIndex="10">
        <cover-view slot="callout">
            <block wx:for="{{clubs}}" wx:key="index">
                <cover-view marker-id="{{item.id}}" class="callout-container" bind:tap="onMarkerTap" data-item="{{item}}">
                    <cover-image src="https://weapp.tempot.com/club-cover.png" class="image">cover-image>

<cover-view class=“title”>{{item.title}}cover-view> cover-view> block> cover-view> map> view>
