Title: [FIXED JENKINS-19803] breadcrumb bar does not move lower than initial position on page

This change compares the initial breadcrumb position before adjusting its `top` position. I thought it was the lowest-risk way to ensure the breadcrumb bar doesn't sink when scrolling up past the top of the page in Chrome/Safari/Opera on OS X. :)
