Pressing ALT+SHIFT+D to split the current pane into two panes causes PWSH to start incorrectly

[JasonWThompson]

Environment

OS Version:
[Environment]::OSVersion

Platform ServicePack Version      VersionString
-------- ----------- -------      -------------
 Win32NT             10.0.19041.0 Microsoft Windows NT 10.0.19041.0

Terminal version: 
Windows Terminal Preview
Version: 1.6.10272.0

Any other software?

pwsh --version
PowerShell 7.1.1

Steps to reproduce

Open up a tab configured to start with Powershell 7.1.1. Press ALT+SHIFT+D

Expected behavior

A new Powershell instance starts in a separate pane.

Actual behavior

I get a pane that says [error 0x8007010b when launching `pwsh.exe']

Other notes

Splitting the broken pane creates a working pane. Splitting that pane gives a broken pane. And so on...

Additionally splitting the pane with ALT+SHIFT+- or ALT+SHIFT+= works every time.

Here's an example of me splitting the pane over and over again. You may need to zoom out since this is from my 4k screen.

I didn't notice this when initially searching for the issue, but this is very similar to #9114 The only difference is that the author of #9114 is duplicating the tab and I'm splitting the pane. I'm guessing the cause is the same.

Yep, these are the same root cause, which is fundamentally #8930.

/dup #8930
