Bug: process-unmapped-keys keeps shifting keys in Windows Terminal

[xudyang1]

Requirements

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

Describe the bug

process-unmapped-keys keeps shifting keys after pressing ctrl+shift+number in windows terminal.

Relevant kanata config

No response

To Reproduce

1. Prepare a basic config file config.kbd:

(defcfg
  process-unmapped-keys yes
)

(defsrc)
(deflayermap (base)
  caps esc
  esc  `
)

2. powershell run kanata -c config.kbd
3. type ctrl+shift+1 to open a new tab with profile index 1
4. type any keys to see the output (e.g., type abcd, but ABCD shown on the screen).

• disable process-unmapped-keys fixes it
  config.kbd:

(defsrc)
(deflayermap (base)
  caps esc
  esc  `
)

Expected behavior

should not shift keys

Kanata version

1.7.0

Debug logs

No response

Operating system

windows 10

Additional context

When keys are shifted, alt+tab twice (switch to another program and switch back) temporarily fixes the shift. Typing ctrl+shift+1 and the bug occurs again.

Does this still reproduce if you try winiov2 variant?
