This is an intentional regression we introduced to make many other major improvements possible, including sixels. It was removed in #17666. The issue happens because Windows 10 ships with PowerShell 6 and PSReadLine 2.0.0-beta3, which contains a bug where the attributes are incorrect. The issue was fixed in this PR that ships with Windows 11: PowerShell/PSReadLine#1626

There's two ways to fix this issue:

• (Recommended) You can install the newer PowerShell 7 here: https://learn.microsoft.com/en-us/powershell/scripting/install/installing-powershell-on-windows
  If you don't have winget installed or don't want to use it, I recommend downloading the MSI package.
• Alternatively, you can run Install-Module PSReadLine and restart all of your PowerShell tabs. If the command fails, it may be necessary to add a -Force parameter.
