Review Comment:
The updated code creates containers with a size of 0B which caused the
balancer to include them in its selection process. This inclusion resulted in
test failures within the `balancerShouldObeyMaxSizeLeavingSourceLimit()` test
case.
To address this issue, a validation condition was implemented within the
FindSourceGreedy#canSizeLeaveSource() method. This condition ensures that
containers with a size of 0B are excluded from consideration by the balancer.
This was tested manually.
