The Japanese difference between "開けてた" and "開けた" is so difficult to translate.

4th panel should be "Wait, had I left the window open...?" then?

By itself, that's definitely less ambiguous. However, in casual usage, I more frequently hear my initial pick for phrasing. The presence of the open window in the scene provides context that Marisa's meaning is "I don't remember opening that window. Did I open it?" and not, "I don't know if the window is open. I meant to open it, but did I?"
