Close Focused Track not working

pa.do('Close Focused Track') doesn't seem to work, though that command works in macros. It's very useful if you want to loop through a bunch of files.
The only way I could get my script to work was to create a macro (cfs) containing only that single command and then use pa.do('Macro_cfs')

Start by reproducing pa.do('Close Focused Track') and compare it with the working macro path using pa.do('Macro_cfs'). Trace how these two entry points dispatch commands; done means the direct command works for looping through files without requiring a one-command macro.
