Description
Issue Type: Bug
This happens whenever I have anything loaded in Powershell with more than a few files.
Whenever I start VsCode and / or kill my session, there is a moment where the .net intelisense work normally.

However, a mere second after, anything from the .net space disappear and I only get the Powershell intellisense instead.

If using VsCode with a single file, it works fine.
As soon as I open a folder containing dozens of Powershell files (within or without a workspace), it work briefly as the session load, then break.
To reproduce:
- Clone https://github.com/itfranck/DudDashboard
- Start VSCode
- Open a ps1 file
- Type [System. then press space
For a few seconds, Collections / Threading / Net and other .Net namespace will be available.
If you repeat the operation a few time, the .Net namespaces stop being suggested and only Powershell suggestions occurs.
This happened for a few months with both Powershell and Powershell Preview extension and with both VsCode and VsCode insiders.
Here are the logs :

Context :
- I opened vscode
- I loaded my workspace containing my project
- I typed [system. then pressed CTRL + Space to force intellisense then I saw .net elements shown there and pressed Escape to close the intellisense.
- Powershell integrated console message showed in the terminal
- I pressed CTRL + Space again
- Intellisense showed again, but this time, all .net related suggestion had disappeared.
If there's any addtional logs I can include to provide more insight, I will be happy to.

Research direction
Reproduce the failure in a VS Code workspace using the DudDashboard repository, comparing a single PowerShell file with a folder containing many files. Start by reviewing the attached logs and the extension behavior around repeated IntelliSense requests. Done means .NET namespace suggestions remain available after the PowerShell session loads and after IntelliSense is reopened.
