Starting PowerShell extension from VSCode results in PSReadLine error

Prerequisites

• I have written a descriptive issue title.
• I have searched all open and closed issues to ensure it has not already been reported.
• I have read the troubleshooting guide.
• I am sure this issue is with the extension itself and does not reproduce in a standalone PowerShell instance.
• I have verified that I am using the latest version of Visual Studio Code and the PowerShell extension.
• If this is a security issue, I have read the security issue reporting guidance.

Summary

When starting the PowerShell extension from VSCode, PSReadLine repeats the same error half a dozen times, and during early use of the terminal.

I have filed the issue with PSReadLine, but as the PowerShell extension was last released yesterday, and I cannot reproduce the problem when running from pwsh in VSCode or Windows Terminal, it appears to be an error with the plugin.

Steps to Reproduce

1. Start Visual Studio Code
2. Make sure the PowerShell extension is loaded. (Easiest way seems to be to open a .ps1 file in an editor tab.)

Looks like that fixed it. The issue does NOT reproduce with v2022.10.2. (The issue still reproduces with v2022.10.1, however.)

Thanks for fixing this @andschwa, I really appreciate it!

Hi @cdonnellytx! I think we just got this fixed in the PowerShell Preview for VS Code. Could you verify if this issue still reproduces using the preview extension?
