It's how Tesla did it, but it's not inherent in frameless designs. The problem is that materials flex, and if the window isn't seated in a track around it, air/water will come through in certain circumstances, and also cause drag. So Tesla chose to have them seat themselves when the door is closed.There are physical buttons for the windows. The frameless design of the windows necessitates lowering them slightly when opening/closing the door to prevent damage.
To be honest, it's in some ways superior to a framed window, because that frame, while it flexes less than glass alone, still flexes and causes leaks and more aerodynamic interference. Unless seated in... etc.
