No, not at all. As the earth comes from the door lock switch harness, it only gets an earth when the door is open then goes off when the door is closed (They work exactly the same as the front door lights).
To clarify, the positive connection to the electric window motor means that's it's only live when the car is unlocked (or up to 30 seconds after the car is locked and alarmed, then no live). Then with the door lock switch it only sees an earth when the door is open. When the door is closed, the door lock switch doesn't have a route to earth (it's what switches on the interior lights and also shows the pictogram on the dash for door open warning).
