Terminal env vars (WT_SESSION, etc) aren't set when set as the Default Terminal #13006
Description
Windows Terminal version
1.12.10983.0
Windows build number
10.0.22000.0
Other Software
No response
Steps to reproduce
Change settings to launch terminal instead of command shell.
Close instances of terminal
Run powershell/pwsh
Check $env:WT_PROFILE_ID
See that it is blank
Expected Behavior
$ENV:WT_PROFILE_ID should never be blank, because having a blank profile ID disables changing settings for that profile.
Actual Behavior
$ENV:WT_PROFILE_ID is not set when terminal is launched with pwsh/powershell, after changing system settings.
