The shell renders its loading bar whenever progressBarMode is not 'none', but the field was declared without an initial value. It was therefore undefined when the shell was created, and the bar was drawn before any request had begun. ProgressBarService emits through a plain EventEmitter, so the shell receives nothing when it subscribes and has to wait for the next emission. On a route that issues no requests of its own, such as Home, that emission never arrives and the bar animates indefinitely. Initialise progressBarMode to 'none' so the bar stays hidden until the service reports a request in flight. Add a spec covering the shell's rendered output for the initial state, a single request, and overlapping requests.

Description
Problem
The shell's loading bar is displayed on the Home page and never goes away. The page has finished loading and nothing is pending, but the animated bar keeps running under the toolbar until the user navigates elsewhere.
Changes Made
progressBarModeto'none'so the bar stays hidden untilthe service reports a request in flight.
shell.component.spec.tscovering the shell's rendered output forthe initial state, a single request, and overlapping requests. The spec
stubs the shell's child components so the real template, and therefore
the real progress bar condition, is exercised.
