Annoying animation when pasting long string into PowerShell

Prerequisites

• I have written a descriptive issue title.
• I have searched all 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.

Summary

I’ve had this problem since I started using PowerShell. When I try to paste a long string (usually a path) into PowerShell, it always plays a typewriter animation and I have to wait until it’s done.

I am not confident that the problem is with this plugin, but PowerShell works fine after I disabling it, so I guess it’s not a VSCode or terminal issue. The Terminal.app that comes with macOS is also fine.

Is there any way we could remove this animation? This is almost the only reason I don’t use PowerShell.

No, it does not happen in a regular pwsh console inside and outside of VS Code. PSReadLine is definitely activated: $PROFILE:

...
Set-PSReadLineOption -EditMode Vi
Set-PSReadlineKeyHandler -Key Tab -Function MenuComplete
...

Thank you, it is much, much better. But on my Raspberry Pi 400 (Debian Bullseye AMD64), the last 5 or 6 chars are still appearing with a delay. This is regardless how long the pasted string is. The first n-6 chars appear instantaneously, the last 6 chars char by char. I will try to make a screen capture later today.
