Windows Terminal version

1.23.12371.0

Windows build number

10.0.19045.0

Other Software

PowerShell 5.1
PowerShell 7.5.3
PowerShell-Preview 7.6.0-preview.4

Steps to reproduce

run powershell/pwsh in wt and then run in that session

$host.ui.RawUI.WindowTitle = 'NewTitle'

then run to check this sets in WT & passes through properly to the powershell process

get-process -Name WindowsTerminal,pwsh,powershell | Select-object name,id,MainWindowTitle

Expected Behavior

The powershell/pwsh processes that are running in WT should also return the updated window title updated & not a blank entry when queried using Get-Process

Actual Behavior

MainWindowTitle of the pwsh process running in wt returns blank (others are running in conhost)
