Yes. The additional tests are used to test these bugs we found in this PR.
For example, `fastSquaredDistance(v2, norm2, v4, norm4, precision)` is used to
test the case where two `SparseVector`s have different indices which is the
major bug you mentioned.
Original test only contains the cases of `SparseVector` vs. `DenseVector`
and `DenseVector` vs. `DenseVector`. The additional test includes comprehensive
tests for different combinations.
