【报Bug】amap show-location 设置初始scale为18的时候不显示

示例代码：

    <view class="map-container">  
        <map   
            :latitude="latitude"  
            :longitude="longitude"

            :enable-overlooking="enableOverlooking"  
            :enable-traffic="enableTraffic"  
            :show-location="showLocation"  
            @tap="amapTap"  
        ></map>  
    </view>  
</template>  

<script>  
    const amapFile = require('./../../components/amap-wx/amap-wx.js');

        key: 'XXXXXX'  
    });  
    export default {  
        data() {  
            return {  
                latitude: 0, // 纬度  
                longitude: 0, // 经度  
                scale: 16, // 放大程度  
                enable3D: true, // 3D楼快  
                enableSatellite: false, // 卫星图

        onLoad () {

                },  
                fail: (info) => {
