I had a Mazda with this feature, apparently very common among Japanese cars in the early 90s. At first I thought it was broken, until I started looking into how to fix it and found you just have to pull the handle as you're closing the door to stop it from popping up. It's supposed to make you think about grabbing your keys but after a while it sort of became automatic. I've got an early 80s SAAB that handled this in a more straightforward way. The driver's door lock plunger will not go down while the door is open, forcing you to lock it with the key (or reach around from another door, and then lock that.)
