Manual testing scenarios

1. Open customer account login page in Firefox or IE browser.

Hi @dankhrapiyush, thank you for collaboration.
Can you please remove trimUsername declaration from requirejs-config.js and use path Magento_Customer/js/trim-username obviously inside .phtml.

@VladimirZaets Removed trimUsername declaration from requirejs-config.js and used path Magento_Customer/js/trim-username inside .phtml.

I'm not getting why the Travis CI build could not complete.

Thank you.

@dankhrapiyush thanks. Currently, we have some problem with Travis. It isn't PR problem.

[dankhrapiyush]
