mergeVertices updates v0, v1, v2 but not the parallel vertice array faces.vertices[]

What steps will reproduce the problem?
1. When TriangleMesh3D.mergeVertices() finds a duplicate vertice it 
updates faces with the new v0,v1,v2 but not the parallel array vertices[] 
which I assumed should contain the same vertices.  Instead of using 
v0,v1,v2 I looped throught the array and did not get what I expected.

2. Inspect the code, TriangleMesh3D.mergeVertices, line 325 (or close to 
it)

for each( var f:Triangle3D in geometry.faces )
{
    f.v0 = uniqueDic[ f.v0 ];
    f.v1 = uniqueDic[ f.v1 ];
    f.v2 = uniqueDic[ f.v2 ];
}

****should be********

for each( var f:Triangle3D in geometry.faces )
{
    f.v0 = uniqueDic[ f.v0 ];
    f.v1 = uniqueDic[ f.v1 ];
    f.v2 = uniqueDic[ f.v2 ];
        // update vertice array also
        f.vertices[0] = uniqueDic[ f.v0 ];
        f.vertices[1] = uniqueDic[ f.v1 ];
        f.vertices[2] = uniqueDic[ f.v2 ];
}

What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?

Please provide any additional information below.
