execCut and execPaste commands not working in custom keybindings in 1.101?

[pokutuna]

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

• VS Code Version: 1.101.0 (dfaf44141ea9deb3b4096f7cd6d24e00c147a4b1, arm64)
• OS Version: macOS 14.7.1 (23H222)

Steps to Reproduce:

1. Launch VS Code in clean environment: code --disable-extensions --user-data-dir=$(mktemp -d) .
2. Create custom keybindings using execCopy, execCut and execPaste commands
3. Add the following to keybindings.json:

[
  {
    "key": "ctrl+1",
    "command": "execCopy"
  },
  {
    "key": "ctrl+2",
    "command": "execCut"
  },
  {
    "key": "ctrl+3",
    "command": "execPaste"
  }
]

4. Try to use the custom keybindings (Ctrl+1 to copy, Ctrl+2 to cut, Ctrl+3 to paste)

Expected Result:

• Ctrl+1 should copy the current selection
• Ctrl+2 should cut the current selection
• Ctrl+3 should paste the content from clipboard

Actual Result:

• The keybindings do not execute the copy/cut/paste operations
• No error messages are displayed

More Info:

• This worked in VS Code 1.100.3 (258e40fedc6cb8edf399a463ce3a9d32e7e1f6f3, arm64) but fails in 1.101.0 (dfaf44141ea9deb3b4096f7cd6d24e00c147a4b1, arm64)
• Keybindings are recognized in Keyboard Shortcuts settings but do not execute
• No error messages or console errors appear
• Default Cmd+C/Cmd+x and Cmd+V "Copy"/"Cut"/"Paste" work normally
• editor.action.clipboardCopyAction and others work in custom keybindings
• I noticed this while using complex keybindings and created this simple reproduction case

I suspect this might be user error on my env since such basic functionality not working seems unlikely, but the issue persists even in the cleanest possible environment.
