istanbul ignore annotation does not work in coverage

Hello, I have next dependencies installed for project: dependencies.txt And here is my karma.conf.js: karma.conf.txt I have next block of code:

    /* istanbul ignore next */
    function appMenu(MenuService) {
        /* istanbul ignore next */
        return MenuService.loadAppMenu();
    }

And here is the Coverage summary:

Statements : 87% ( 87/100 ) Branches : 62.5% ( 5/8 ) Functions : 44.44% ( 4/9 ) Lines : 87% ( 87/100 )

And here is a screenshot from html report:

At the bottom of html report I see: Code coverage generated by istanbul

I tried different ways to ignore these two lines from coverage report:

Could anyone help me to find a solution how to use ignore line/statement/branch from coverage report? Thank you.
