Velocity chart show wrong committed story points if issues are coming from another sprint and removed during the sprint

Issue Summary

Velocity chart show wrong committed story points if issues are coming from another sprint and removed during the sprint.

Steps to Reproduce

1. In a Scrum project create 2 stories and 2 sprint (sprint a and sprint b)
2. Add the 2 stories to sprint a, estimate them with 3 story points each but don't start the sprint.
3. Move the 2 stories to sprint b and start sprint b.
4. While sprint b is still open, move one of the 2 issues out of the sprint.
5. Complete sprint b.
6. Open the Velocity Chart and observe that the gray bar with the committed story points only show 3 story points when there should be 6. The Story points committed for the issue which is moved out from the sprint b while was still in progress are not anymore included in the gray bar:
   

Expected Results

As default behaviour, the gray bar in velocity chart for each sprint shows the total estimate of all issues in the sprint when it begins disregarding if some are removed before the end of the sprint.

Actual Results

Velocity Chart doesn't show committed story points if issues are coming from another sprint and removed during the sprint.

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
