1. Create a freestyle project 'foo' with a shell build step that executes sleep 30 and save.
2. Click 'Build Now'
3. Go to the build's page (/job/foo/1) and wait until the build finishes.
4. From the breadcrumb bar, select 'Build Now' from the 'foo' job's context menu.
5. Wait a second (so the build is actually started), then reload.

Expected result: 'Next Build' link is shown
Actual result: It's not

If you open the job's main page at /job/foo e.g. in another tab, then reload the build page again, the 'Next Build' link appears after reloading.
