spawn new tab in quake window with `wt -w 0`

### Windows Terminal version (or Windows build number)

Microsoft Windows NT 10.0.22000.0 (Windows 11 dev preview)

### Steps to reproduce

open quake window with windows + `

Run wt -w 0 nt

### Expected Behavior

Opens new tab in same window.

### Actual Behavior

Opens a new tab in a separate window → follow-up commands use that same window.

#### PS.
(if this is a dupe, I swear I searched)

Reproduce the issue by opening the quake window and running `wt -w 0 nt` on Windows 11. Trace the Windows Terminal command-line handling for the `-w 0` target; done means the command opens a new tab in the existing quake window rather than a separate window.
