Unable to tap use-defsrc

[zachpoblete]

I'm trying to make a layer where even if you hold a key, it just taps it. But I'm unable to get Kanata to recognize tapping use-defsrc (through a virtual key). When using the config below, pressing any key outputs nothing.

(defsrc
  q w e r t  y u i o p
  a s d f g  h j k l ;
  z x c v b  n m , . /
)

(defvirtualkeys use-defsrc
  use-defsrc
)

(deflayermap (tap)
  _ (on-press tap-vkey use-defsrc)
)
