Cannot remap a sequence of 3 keys or more

Describe the bug
My config has

 "vim.normalModeKeyBindingsNonRecursive": [
      {
          "before": ["<leader>", "z", "o"],
          "after": [],
          "commands": [
              {
                  "command": "workbench.action.closeOtherEditors"
              }
          ]
      },
]

When I press space z o, the space z is first handled separately and does nothing, and then o is handled, which adds a new line. Instead I would like my newly-defined command to work.

My trace logs:

Expected behavior
I would have expected my command space z o to apply the vscode command i defined in the remap.

• Extension (VsCodeVim) version: 1.29.0
• VSCode version: 1.85.2
• OS: MacPro M2

Additional context

I tried to instead setup keybindings in keybindings.json to do what I want. But it seems like if I define a keybinding there that starts with my vim <leader> key, the vscode-vim bindings stop working entirely.

No source files or tests are named. Reproduce the configuration and trace the normalModeKeyBindingsMap handling shown in the logs; done means a three-key mapping such as space z o reaches the configured VS Code command without handling the prefix separately.
