Android TV Emulator KEYCODE_DPAD_CENTER event not dispatched

Question

When using the Android TV (1080p) 29API virtual device I've found that the KEYCODE_DPAD_CENTER KeyEvent is never fired. It also doesn't cause a button click event to fire either.

    override fun dispatchKeyEvent(event: KeyEvent?): Boolean {
        if (event != null) {
            when (event.keyCode) {
                // This first match is never hit
                KeyEvent.KEYCODE_DPAD_CENTER -> Log.d("DPAD", "Center")
                // The rest of these all work fine
                KeyEvent.KEYCODE_DPAD_UP -> Log.d("DPAD", "UP")
                KeyEvent.KEYCODE_DPAD_DOWN -> Log.d("DPAD", "DOWN")
                KeyEvent.KEYCODE_DPAD_RIGHT -> Log.d("DPAD", "RIGHT")
                KeyEvent.KEYCODE_DPAD_LEFT -> Log.d("DPAD", "LEFT")
            }
        }
        return super.dispatchKeyEvent(event)
    }
