Using tap-hold, no output with multiple modifiers and 1 key tapped

[IanEdington]

I have 3 tap-hold keys in my setup, space and the two keys on either side. All the modifiers work with all the other keys, and a single tap-hold modifier works with any of the other tap-hold key. However, holding two tap-hold modifiers and tapping the 3rd tap-hold key doesn't do anything.

using evtest with the "My Kmonad Output" I get:

Hold	Tap	Expected	Actual
@met_ret	@met_spc	met+spc	met+spc	✅
@met_spc	@met_ret	met+ret	met+ret	✅
@met_ret+@ctl_esc	a	met+ctl+a	met+ctl+a	✅
@met_ret+@ctl_esc	@met_spc	met+ctl+spc	met+ctl	❌

(defcfg
  output (uinput-sink "My KMonad output")
  cmp-seq lalt
  cmp-seq-delay 5
  fallthrough true
  allow-cmd true
)

(defsrc lalt spc ralt)

(defalias
  ctl_esc (tap-hold-next-release 200 esc lctl)
  met_spc (tap-hold-next-release 200 spc rmet)
  met_ret (tap-hold-next-release 200 ret lmet)
)

(deflayer qwerty @met_ret @ctl_esc @met_spc)
