Leader mappings stop resolving after using VS Code debugger until window reload

[fauceta]

Description

After using the VS Code debugger, VSCodeVim stops resolving custom leader mappings until the window is reloaded.

Important detail: Vim itself is still active and still receives keys.

• Pressing <space> is still recognized as leader
• The Vim log shows both keys being handled
• Built-in Vim motions like w, b, and text objects such as ci( still work
• Native VS Code shortcuts like Ctrl+Shift+P still work
• Only custom leader mappings stop working
• Developer: Reload Window restores the mappings immediately

Environment

• VS Code version: 1.117.0
• VSCodeVim version: 1.32.4
• OS: Windows

Minimal configuration

{
  "vim.leader": "<Space>",
  "vim.useCtrlKeys": true,
  "vim.normalModeKeyBindings": [
    {
      "before": ["leader", "f"],
      "commands": ["workbench.action.quickOpen"]
    }
  ],
  "vim.normalModeKeyBindingsNonRecursive": [
    {
      "before": ["leader", "<Space>"],
      "commands": ["workbench.action.showCommands"]
    }
  ]
}

Steps to reproduce

1. Configure:
   • <space> f -> workbench.action.quickOpen
   • <space> <space> -> workbench.action.showCommands
2. Verify both mappings work.
3. Start and use a debug session.
4. Return to the editor.
5. Try the mappings again.

Result: mappings no longer execute until Developer: Reload Window.
