In Jenkins 2.375.1 and above the dropdown chevrons in the breadcrumb bar no longer work in Google Chrome (running on Linux). They are not clickable links at all for any levels of breadcrumbs. The chevrons do work in Firefox, however those have a different issue (they are transparent and difficult to read). I have attached 3 screenshots showing the behavior in 2.364.1 (on Google Chrome), the behavior in 2.407 (also on Chrome), and the behavior in 2.407 in Firefox.
