breeze.linalg.SparseVector.equals always return true may bring error.

I implemented an iterative graph algorithm with 'breeze.linalg.SparseVector' just like 'Graph.staticParallelPersonalizedPageRank' does. However, the algorithm can not iterate correctly and I finally found that is because 'breeze.linalg.SparseVector.equals' will always return 'true' if two vectors have the same dimension.

scala> val zero =  SparseVector.zeros[Double](10)
zero: breeze.linalg.SparseVector[Double] = SparseVector(10)()
scala> val vec = SparseVector(10)((0, 1.0))
vec: breeze.linalg.SparseVector[Double] = SparseVector(10)((0,1.0))
scala> zero == vec
res2: Boolean = true

Does that bring the same error for 'Graph.staticParallelPersonalizedPageRank' ?
