Requirements

• I've searched platform-specific issues, issues and discussions to see if this has been reported before.
• My issue does not involve multiple simultaneous key presses, OR it does but I've confirmed it is not key rollover or ghosting.

Describe the bug

On macOS with 'Delay until repeat' so to the shortest value the attached config sporadically causes chatter.

Given the config and simulator input we get:

out:   ↓(press) D
t:              286ms
out: ↑(release) D

Intuitively I would expect the out: ↑(release) D event to occur at the same time as the physical key is released as shown in the Expected behavior output.

Hopefully this is a valid bug-report and not my mental model being out of alignment :).

Relevant kanata config

(defalias
  nav (tap-hold-release 50 250 spc (layer-while-held svnav))
)

(defsrc
  d
  spc
)

(deflayer qwerty
  d
  @nav
)

(deflayer svnav
  d
  spc
)

To Reproduce

Run in simulator with following input:

d:KeyD t:35 d:Space t:5 u:KeyD t:250 u:Space t:5

Expected behavior

Expected simulator output, basically as if space was never pressed:

out:   ↓(press) D
t:              35ms
out: ↑(release) D
