Description

Step to reproduce.

1. Add a large folder to a composition.
2. A little window appears with a progress bar going left and right, click on the exit button to close this window.
3. Your folder has been partially added, select it in the composition view.
4. Delete it using the "-" button.

Result: The progress bar indicating the size of the composition is no updated accordingly to the last deletion, it still shows a high value even if the composition is now empty.
