They do make some with overflow holes. Danze has a whole line of themThe problem with that popup is they are made for vessel sinks and do not have an overflow drain slot.
The picture you showed, shows it should have a pop up. is there a removable plug on the back side of faucet? Why did it not come with the pop up?I'd have a problem when I have to use my hand to open the stopper, then rinse again. Also, I put new American Standard vanity faucet with cable operated stopper. The stopper is a standard one, but it is still heavy enough to push down on its own. It is enough to create a poor drain. This faucet also has flex supply with little more than 1/8 i.d. tubes. When toilet is flushed, it gets no cold water.
