Bokkmarks closeKantu true but kantu windows remain opened

I use this bookmarks, it works but at the end of macro do not close Kantu Window

I see closeKantu true in the javascript

javascript:(function()%20{try%20{var%20evt%20=%20new%20CustomEvent(‘kantuRunMacro’,%20{detail:%20{name:%20"PATHMACRO\MACRONAME",from:%20’bookmark’,storageMode:%20’xfile’,closeKantu:%20true}});window.dispatchEvent(evt);}%20catch%20(e)%20{alert(‘Kantu%20Bookmarklet%20error:%20’%20+%20e.toString());}})();

Why kantu windows do not close automatically ?

I use firefox ESR 60 (it’s firefox 68)

NOTE: The %20 was added by deault from firefox when i save the bookmark, in original was space " ".
