Busy indicator shown only in Projects view opened before the project

1. Don't have any project open.
2. Go to Edit mode.
3. Open one Projects view.
4. Open a project.
5. Open a second Projects view.
6. Change the build configuration.
   A busy indicator will be shown next to the project's name in the Projects view that you opened in step 3. The view opened in step 5 will not show this indicator.
7. Close the project.
8. Reopen the project.
9. Change the build configuration.
   Now both Projects views will display the busy indicator.

It should not matter when such a view was opened. They should always show the same.
