Assuming that the mouse pointer is parallel to the display and that a light themes is used, the visual click zone is positioned below and to the right of the upper left corner.
E: correct content
E₂ (correction): The visual click zone should be more than 1 px², but it’s not misaligned.
If I understand correctly then you are assuming that the mouse cursor is hovering and not just thick.
Good take, I vote the mouse crusor on screen is just thick.
Thus there is no “misalignment” at the pointer tip and the screen or shadow “below” the mouse crusor.
