Windows Terminal version

1.23.12811.0

Windows build number

10.0.19045.3448

Other Software

No response

Steps to reproduce

Run WindowsTerminal.exe (or WT.exe) with default settings (note: work in background mode is OFF)

in Powershell window [default profile]
press key 'ContextMenu' on keyboard

in context menu choose 'Close Tab' and click by left key mouse

Expected Behavior

latest good release:
terminal-1.22.11751.0 and earler

latest good canary
terminal-1.24.531.0 and earler

If we work not in background mode and close Latest Tab, process WindowsTerminal.exe must be closed

Actual Behavior

with trouble release:
terminal-1.23.12681.0
terminal-1.23.12811.0

with trouble canary all since terminal-1.24.551.0 -> terminal-1.25.2821.0

check processes in OS, and see what the parent process of WT does not terminate.
And we see app with default ico on taskbar Windows.

WT Hotkeys Alt+F4 and Ctrl+Shift+W, work fine, closed all (parent and child processes).
command 'exit' in PS windows closed all.
closing the last tab by clicking on the window cross also works great.
