xr-frame 组件，对于同时识别多物件时，是否会存在降低识别率的问题？目前是否有对应的解决方案？
<xr-ar-tracker mode="Marker" wx:for="{{markerList}}" wx:for-item="markerItem" id="marker-{{markerItem.id}}" src="{{markerItem.markerImg}}" bind:ar-tracker-switch="handleTrackerSwitch"> <xr-mesh wx:if="{{markerItem.id === 11}}" geometry="plane" material="mtlAll" position="0 0.2 0" scale="3 3 3" states="alphaMode:BLEND" /> </xr-ar-tracker>
