Control key getting "stuck" for enter/tab key?

Nobody has claimed this yet.

### Windows Terminal version

1.18.3181.0

### Windows build number

10.0.22631.0

### Other Software

_No response_

### Steps to reproduce

`Winget install ‘KDE.Kdiff3’`

Open razzle (not sure if this matters)

`Git config --edit --local`

```
[diff]
tool = kdiff3
autoRefreshIndex = true
[difftool]
prompt = false
[difftool "kdiff3"]
path = C:/Users/jeffmill/AppData/Local/KDiff3/bin/kdiff3.exe
cmd = \"C:/Users/jeffmill/AppData/Local/KDiff3/bin/kdiff3.exe\" \"$LOCAL\" \"$REMOTE\"
```

(modify paths accordingly, of course)

`git difftool 66f7252e212f6~1..66f7252e212f6`

(use a suitable diff that contains multiple changes in it)

Kdiff3 will open and block the console.

Focus on terminal window and press Ctrl-Break

Focus on Kdiff3 window and press Ctrl-Q

Focus on Terminal window and Press Enter a bunch of times – you should see “mmmm”

### Expected Behavior

enter key should work as expected.

### Actual Behavior

mmmm is shown.

Start by reproducing the reported sequence with Windows Terminal 1.18.3181.0: run the KDiff3 git difftool, send Ctrl-Break and Ctrl-Q, then press Enter repeatedly. Trace how the terminal handles those key events and verify that Enter no longer produces repeated “m” characters.
