[Mac] Caps lock does not work on OSK

[tombogle]

The OSK in Keyman for macOS shows a Caps Lock key, but it does nothing. Clicking it does not turn on the Caps Lock light on the physical keyboard, nor does pressing Caps Lock on the physical keyboard cause the Caps Lock button to display depressed on the OSK. Furthermore, activating Caps Lock on the physical keyboard does not cause key clicks on the OSK to produce the shifted characters (but with the OSK displayed any keypress on the physical keyboard does take the Caps Lock state into consideration. Admittedly, this is low priority, especially since the shift key on the OSK essentially functions as a Caps Lock, but the behavior is unexpected and differs from the behavior in the Windows version.

Interestingly enough; clicking the Caps Lock on Windows does work, but it still doesn't light up.
