The `show_command_palette` command does not work in some contexts

Description

The show_command_palette does always not work when used in some menus, including Branch.sublime-menu and Tag.sublime-menu.

Steps to reproduce

Steps to reproduce the behavior:

1. Add a debug git command, e.g. by adding to ~/.gitconfig:

   [alias]
     echo = "!echo"

2. Add to Sublime Merge\Packages\User\Branch.sublime-menu:

   [
     {
       "caption": "Debug: Echo text...",
       "command": "show_command_palette",
       "args": {
         "command": "git",
         "args": {"argv": ["echo", "$text"]}
       }
     }
   ]

3. Open a 'normal' Git repo in Sublime Merge (has a commit on a branch)
4. Right click on a commit in the Commits panel that has a branch, then use the newly-added debug command

Expected behavior

The command palette should open, allowing the user to input text.

Actual behavior

The git echo command runs with empty $text, skipping the command palette entirely.

Note: The command actually works correctly when used from a branch in the Locations panel.
