Testing Instructions

• Go to V2 project layers list
• Update layer visibility for one or multiple layers by switching on or off the eye icon
• Go to project's nested components (like going to analysis list, going to a specific layer, etc), then go back to layers list. Make sure the visibility statuses of layers still persist
• Navigate away from project UI, or just refresh. Go back to project layers list UI, the visible layer should just be the default layer.
