indexing with SparseArray with bool dtype may return incorrect result because of some internal conversions.

arr = pd.SparseArray([1, 2, 3]) indexer = pd.SparseArray([True, False, True], fill_value=False, dtype=bool) # NG arr[indexer] # [2.0, 2.0] # Fill: nan # IntIndex # Indices: array([0, 1], dtype=int32) # Expected (after this PR) arr[indexer] # [1.0, 3.0] # Fill: nan # IntIndex # Indices: array([0, 1], dtype=int32)

API: SparseSeries comparison now returns sparse
51b20de 
Because #13985 has been fixed, ``SparseSeries`` comparison op now can return ``SparseSeries`` (it returns normal ``Series`` on current master). also fixed a bug when ``SparseArray`` created from ``SparseSeries`` may not inherit ``dtype``. Author: sinhrks <sinhrks@gmail.com> Closes #13999 from sinhrks/sparse_comparison and squashes the following commits: eafc94c [sinhrks] API: SparseSeries comparison now returns sparse
