Where new layer adds, it's cover other layers and intercepts mouse events, although it is not subscribed to they and hasn't event handlers.
Visual covering i decided by new layer opacity. But i don't know how set transparency for mouse events to new layer.
I need to disable mouse events intercepting for new layer, and that other layers can process they.
newLayer.disableMouseEvents don't help.
Is perhaps to set mouse transparency for FeatureLayer or other layer types? Only thought is throwing mouse events from new layer to other layers in some way.
