Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.57.0
• OS Version: Ubuntu 20.04 (5.4.0-42-generic)
• Bash Version: 5.0.17(1)-release
• Zsh Version: 5.8

Steps to Reproduce:

1. Open ubuntu terminal and start vscode: code --disable-extensions.
2. Open vscode terminal with bash or zsh.
3. Input cat command and enter.
4. Press alt+shift+h keys, and it shows up ^[h.

What I expected to see is ^[H with alt+shift+h pressed.
And ubuntu terminal shows the correct keys codes.
