Search Core Commands receives unexpected argument

[Unknow0059]

Description of the bug

Lines 2-8 of CommandsBrowser.sublime-commands contain "Search Core Commands", displayed for interaction in the Command Pallette.

If I place that in my .sublime-menu file - for the right click context menu - and click the button, the following error appears:

Traceback (most recent call last):
  File "...\tools\Lib\python38\sublime_plugin.py", line 1657, in run_
    return self.run(**args)
TypeError: run() got an unexpected keyword argument 'event'

Note ... is the installdir for Sublime Text 3.

Steps to reproduce

1. Copypaste Lines 2-8 into the .sublime-menu file
2. Click respective button in context menu

Expected behavior

List of Core commands to be shown.

Actual behavior
