Yes, iTerm2 does not have this problem. While unsetopt PROMPT_SP removes the %, the blank lines are still echoed. The easiest way to test this is to touch ~/.hushlogin and open Terminal.app. Notice the scrollbar.
So, PROMPT_SP is definitely not the problem. It seems the prompt is being pushed down by the blank lines. Hence why % is not being overwritten by the prompt in the screenshot.
