Description

When both Shift keys are held down, releasing one produces a key-event% for which get-key-code produces 'shift or 'rshift, not 'release. This is causing client code (e.g. 2htdp/universe) to misidentify the release as a keypress.

Research direction

Start by tracing the key-event% and get-key-code behavior described in the issue, then check how 2htdp/universe consumes the resulting event. Reproduce the case where both Shift keys are held and one is released; done means that release is identified as 'release rather than 'shift or 'rshift.
