Error description

• Headline:
  
  rebase fails to propagate new baseline dependency hierarchy
  
  Description:
  
  When a component is included at multitple points in a baseline
  dependency tree,
   and a stream based upon the root composite baseline has also
  made baselines in the same component
   and the parent stream removes the component from one of its
  inclusion points
   and the child stream rebases onto the new root composite
  baseline
  Then a new baseline in the child stream will still have that
  component included at its multiple inclusion points.
  
  Steps to reproduce:
  ---------------------
  =? Create C1, C2, C3, C4 components and projects C1_MAIN,
  C2_MAIN, C3_MAIN and C4_MAIN. Create 2 or 3 baselines on each
  component.
  
  =? Create composite component COMP_BLD and create a read only
  project         called 'COMP_INT_Proj'. And do edit baseline
  dependency as below.
  COMP_BLD
    C1
    C2
  
  =? Create build tree composite component BuildTree_BLD and
  create a read only project called 'Project_1' and do edit
  baseline dependency as below. Baseline shall be
  BuildTree_BLD_BL1_Project_1_Int
  BuildTree_BLD
    C3
    COMP_BLD
      C1
      C2
  
  =? Create second buildtree project 'Project_2' using Project_1
  baseline 'BuildTree_BLD_BL1_Project_1_Int'. Override component
  C3 and make baseline on Project_2.
  
  =?Go Back to Project_1. Now add C4 under BuildTree_BLD by using
  edit baseline dependency as below. And make a baseline. Baseline
  shall be 'BuildTree_BLD_BL2_Project_1_Int'
  BuildTree_BLD
          C3
          C4
          COMP_BLD
                  C1
                  C2
  
  =? Go back to project 'COMP_INT_Proj' and add C4 under COMP_BLD
  and make one baseline.
  COMP_BLD
    C1
    C2
    C4
  
  
  =? Go to project 'Project_1' and rebase COMP_BLD which is
  created on  COMP_INT_Proj. And make one baseline. Baseline shall
  be
  BuildTree_BLD
          C3
          C4
          COMP_BLD
                  C1
                  C2
                  C4
  
  =? Go to project 'Project_2'. And rebase to project_1 baseline
  (BuildTree_BLD_BL3_Project_1_Int). Now override C3 again and
  make one baseline.
  BuildTree_BLD
          C3
          C4
          COMP_BLD
                  C1
                  C2
                  C4
  
  =?Go to project 'project_1'. And remove the C4 from
  BuildTree_BLD by using Edit baseline dependency window. And make
  one more baseline 'BuildTree_BLD_BL4_Project_1_Int'.
  BuildTree_BLD
          C3
          COMP_BLD
                  C1
                  C2
                  C4
  
  =?Go to project 'Project_2'. Rebase to baseline
  'BuildTree_BLD_BL4_Project_1_Int'. After this step you can see
  C4 will be always present in Edit Baseline Dependency window.
  BuildTree_BLD
          C3
          C4
          COMP_BLD
                  C1
                  C2
                  C4
  'cleartool mkbl' in now says 'no new baselines are needed'
  
  At this point, if you go to Properties of Stream ?
  Configuration, it says
  BuildTree_BLD
          C3
          COMP_BLD
                  C1
                  C2
                  C4
  now rebase to a new override of C4 to make a new baseline
  necessary.
  Make a new baseline. Then show its properties.
  The hierarchy matches the most recent 'Edit Baseline Dependency
  window', not the most recent 'Stream Configuration'
  ----------------------------------------------------
  
  Workaround:
  Edit Baseline Dependencies in the child stream and make the
  required change
   (== cleartool mkbl -ddepends ...)
