Ctrl+Backspace keybinding doesn't work inside GH CLI

[alexvy86]

Describe the bug

I have several keybindings configured in my Powershell profile, and specifically the one for Ctrl-Backspace stops working inside Github Copilot CLI. All others keep working normally, but that one starts behaving like a regular backspace instead of deleting whole words.

These are some of the ones I have configured, and all confirmed working in Windows Terminal (pwsh profile) and also inside GHCLI, except Ctrl+Backspace:

Set-PSReadlineKeyHandler -Chord Ctrl+Backspace 	-Function BackwardKillWord;
Set-PSReadlineKeyHandler -Chord Ctrl+Delete    	-Function KillWord;
Set-PSReadlineKeyHandler -Chord Ctrl+u          -Function BackwardKillInput;
Set-PSReadlineKeyHandler -Chord Ctrl+k          -Function KillLine;
Set-PSReadlineKeyHandler -Chord Ctrl+LeftArrow 	-Function BackwardWord;
Set-PSReadlineKeyHandler -Chord Ctrl+RightArrow -Function NextWord;

Affected version

GitHub Copilot CLI 1.0.44-2

Steps to reproduce the behavior

• Open pwsh.exe.
• Configure the Ctrl+Backspace keybinding ( Set-PSReadlineKeyHandler -Chord Ctrl+Backspace -Function BackwardKillWord;)
• Start the GH CLI
• Ctrl+Backspace doesn't work as expected (always deletes single characters)

Expected behavior

Ctrl+Backspace continues working as BackwardKillWord.

Additional context

• OS: WIndows
• CPU architecture: x64
• Terminal emulator: Windows Terminal
• Shell: pwsh.exe

Ah, didn't find #1053 before capturing this. Closing as duplicate of that one.
