Is is possible to determine when SymbolLayer with Images object finished loading?

[keeprock]

I've got a bunch of ShapeSource's SymbolLayer object, which are loading images using Images

<MapboxGL.Images
    images={this.store.images.toJSON()}
    onImageMissing={this.store.addImage}
/>

<MapboxGL.SymbolLayer
        id='markersLevel2'
        filter={['==', 'isRecommended', RECOMMENDATION_LEVELS.SECOND]}
        style={layerStyles.markerLevel2}
    />

Is it possible to detect than images from MapboxGL.Images done loading and presented on a map? If yes, then how?
