Agreed, visibility is improving again, as you stated the latest images show that the shadows from the rover are once again becoming sharper. Agreed far less sever than earlier storms recorded on Mars, but Ingenuity has a tiny solar panel. It has survived many nights without a fully charged battery to power it’s heaters overnight (during the last winter). Staying in one place and particularly after this dust lifting event will mean that some of that dust will be deposited on the solar array as it falls back to the surface. Dust on the array will reduce the charge to the battery. I’d agree that Ingenuity could survive this short dust lifting event, hopefully it will remain in contact with the rover until Perseverance leaves the crater.
