Review: 1.90.0 VSCode Native PowerShell IntelliSense Issues

Prerequisites

• I have written a descriptive issue title.
• I have searched all issues to ensure it has not already been reported.

Summary

1.90 has some new preview PowerShell Intellisense
https://code.visualstudio.com/updates/v1_90#_vs-codenative-intellisense-for-powershell

Should probably make sure there aren't any conflicts with this extension. I'm sure they tested, but still.

This is an overall tracker to open issues over in the VSCode repository if they don't get fixed or aren't being tracked otherwise, so we will need to mitigate or provide warnings in our extension if we detect it is enabled.

VSCode Tracking Issue

Observed Issues

• Font Settings dont work
• Hijacks Tab and Ctrl-Enter PSReadline, doesn't complete in a manner expected by PS
• Repeated Entries observed (e.g. same function listed 3 times)
• Not all completions showing. For instance parameter completion above only shows P parameters even tho I didn't specify that far in the completion.

Start with the linked VSCode tracking issue and the four observed issue links; no repository files or tests are named. Compare the native PowerShell IntelliSense behavior with this extension, track unresolved conflicts in VSCode, and define whether the extension needs mitigation or warnings when native IntelliSense is enabled.
