@zadjii-msft is already working on this.

Since Feb 8, 2024.

### Windows Terminal version

1.18.3181.0

### Windows build number

10.0.22631.2861

### Other Software

_No response_

### Steps to reproduce

1. Set exit behaviour in Terminal to never close automatically by default

> ```json
> "profiles":
> {
> "defaults":
> {
> "closeOnExit": "never",
> ...
> ```

2. Launch a terminal app (a shell/cli editor) from the address bar in File Explorer
3. close it
4. press enter to restart

### Expected Behavior

The respawned process should have the same environment as the original process.

### Actual Behavior

The respawned process launches with the default launch directory of WT, `C:\WINDOWS\system32>`
