Steps to reproduce

When both WT stable and WT preview are both installed, running wt -w 0 sp -s 0.4 pwsh in WT preview will start a WT stable window (or use an existing WT stable window) and split the tab in it.

Even when using the WT preview specific wt.exe, it still doesn't work properly -- it starts a new tab in the current WT preview window and split that tab, while the expectation is that it will split the current tab.

& 'C:\Users\<user-name>\AppData\Local\Microsoft\WindowsApps\Microsoft.WindowsTerminalPreview_8wekyb3d8bbwe\wt.exe' -w 0 sp -s 0.4 pwsh

The command wt -w 0 sp -s 0.4 pwsh works as expected when running in WT stable.
For reference, this behavior was reported in PowerShell/AIShell#363

Expected Behavior

Running wt -w 0 sp -s 0.4 pwsh should split the current tab in the current WT window, regardless of in WT stable or WT preview.

This is expected when the setting in "Manage App Execution Aliases" gives precedence to Terminal Stable

Even when using the WT preview specific wt.exe, it still doesn't work properly -- it starts a new tab in the current WT preview window and split that tab, while the expectation is that it will split the current tab.

This is a bug. I can reproduce it on Canary as well. Thanks!

@DHowett My settings for "Terminal" and "Terminal Preview" are shown below. Does it give precedence to Terminal Stable or Terminal Preview?
