Issue Description

When writing and running some stuff if a open .ps1 file, then going down to the terminal for either pasting or writing anything, a random "@" appear in front.

Reproduce:

• Open a new file
• Write "$Var = 'value'", then F8 to run that line of code
• Go down to terminal, either paste something or start to write.
• A random "@" appears.
• Happens with both saved files and new unsaved files.

Expected Behaviour

No random characters should appear.

Actual Behaviour

Random "@" appear. 100% reproducable.

Duplicate of #2274.

(Understand @ doesn't suggest nice issue duplicates)

The fix for this should be released this month.

(Sorry for creating a duplicate, I tried to search for issues with "@".)

So it could still be weeks until a fix is released?!

Sorry for seeming ungrateful, but. ISE is effectively deprecated since 2017. The stable build of this extension has less features than ISE, so much in fact that I find it limiting compared to ISE. You recommends us to use the preview as it's more feature packed and "as good as stable". For preview/ beta software it would be normal to release builds at a higher cadence, especially with a bug that ruins workflow as much as this does.

Absurd bugs like this, and the fact that I can't have a full working day without the VSCode PS extension crashing or freezing so hard I have to restart VSCode multiple times a day, forces us to keep using legacy Windows PowerShell 5.1 and ISE as it ruins workflow too much. Last problem is true for both the stable and the preview build.

Yes, it's open source and all that. But this ain't good enough for the worlds most profitable company and their own scripting language/ IDE/ extension combo IMHO.
