Recalling a previous command via PSReadLine in VScode is unusable is the prompt contains U+231B in the CaskaydiaCove NF font

Prerequisites

• I have written a descriptive issue title.
• I have searched all open and closed 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.
• If this is a security issue, I have read the security issue reporting guidance.

Summary

(Origin: https://github.com/JanDeDobbeleer/oh-my-posh/issues/4786)

If the prompt contains the character U+231B (Hourglass) ⌛ (using the CaskaydiaCove NF font), when commands are recalled e.g. using the up arrow key, the rendering of the recalled command is incorrect, making editing the command basically impossible:
