[QA] checking width in %

[Jeff Hall]

I haven't had to create a test with this specific type of element 
before, but from some quick Googlin', it seems that there is no specific 
method available via the Selenium API to obtain the width as a 
percentage, so the consensus seems to be that you have to calculate the 
percentage yourself based on the maximum possible pixel width (after 
maximizing the browser window size with something like 
/@browser.window.maximize/)
