Windows 7 guest online resizes downwards

Problem: Even with the guest tools installed and "View | Auto-resize Guest Display" ticked, Windows 7 only resizes downwards and does not resize to 1440p (or larger) fullscreen.
Solution: In the Display tab of the machine's settings, increase the video memory from 48MB to 128MB. (Enabling 3D acceleration is not necessary to fix this problem.)
