Current Behavior:

The top navigation bar is static, and does not update to reflect the current status of the job.

Desired Behavior:

Upon the launch of a new build, the "next" arrow should appear next to the build number in the top navigation bar.

Workarounds:

Manually refreshing the page will eventually result in the arrow showing up, but this is time consuming and inconsistent, as one does not necessarily know when the job starts.
