Dropping a file with AirDrop results in Date Last Opened set to now

I AirDropped a file from an app on my Phone to my new laptop running Sequoia. The **Date Last Opened** was set to the time of transfer. The file was *not* opened on the phone (it’s a newly-generated pdf that offers to be shared by AirDrop, email, etc.). This is new behavior. In OS 13, the Date Last Opened was blank, which is far better for helping me separate unread from read files, including by scripts. Can this new behavior be undone? Is it simply a bug?
