Function key can no longer be bound in macOS

Workaround

Per Jinyu Meng's comment, it is possible to use external software to remap the keys. See that comment for more info.

The bug

Since 17w43a, the Function key can no longer be bound in controls in macOS. Previously, it could be bound and would show up as FUNCTION.

How to reproduce

  1. Go to Options > Controls.
  2. Select a control.
  3. Press the Function key to try to bind the key to the control. Notice that nothing happens; the key press is ignored.
