<leader> key gets stuck when using <leader>m example with bookmarks.toggle

Describe the bug

Using the example for bookmarks remapping, the extension gets stuck in the key.

To Reproduce

Add to the settings.json file:

1. Install bookmarks extension
2. Add to the settings.json file

"vim.normalModeKeyBindings": [
        {
            "before": ["<leader>", "m"],
            "commands": [
                "bookmarks.toggle"
            ]
        },
        {
            "before": ["<leader>", "b"],
            "commands": [
                "bookmarks.list"
            ]
        }
]

3. Try to place a mark using m
4. The leader key now gets stuck (see status bar), and I can't exit back to normal/visual mode or anything, can't type or execute vim commands, so have to reload the window.

Expected behavior

Marks are toggled, can view the marks list

Screenshots

in the gif, once m is pressed, I type on all keys etc. but nothing happens

Environment (please complete the following information):

• Extension (VsCodeVim) version: v1.26.1
• VSCode version: 1.83.1
• OS: Windows 11 (running under WSL2)

Start by reproducing the issue with the settings.json vim.normalModeKeyBindings example and the bookmarks.toggle command, then trace the keybinding handling for m and compare it with bookmarks.list. Done means toggling a bookmark no longer leaves the leader key active, and normal or visual mode commands work afterward.
