Issue Description

If I open a powershell script and make a few edits, I get a message "Formatting PowerShell document..." spinning forever in the footer of VS Code

Meanwhile, the powershell process which is powering the editor features consumes a cull core of CPU:

Attached Logs

EditorServices.log is over 300MB at this point, so hopefully something relevant in there. Do you have a suggested way to share? Or maybe I can just let it run for a few seconds to generate 5-10MB of logs.

Hmmm, it shouldn't get hung like that. Capturing a shorter log file would be helpful, you can e-mail it to me at daviwil at microsoft.com.

In the meantime, you could turn off editor.formatOnType for all languages or just for for PowerShell in your user settings:

"[powershell]": {
    "editor.formatOnType": false
}

Just emailed logs from a short session. Issue repros 100% for me - CPU starts spinning when editing any ps1 script.

Got it! Thanks.
