Update of bug #41512 (project octave):

              Item Group:    Matlab Compatibility => Regression             
                  Status:                    None => Confirmed              
                 Summary: Take max of sparse logical matrix => max() of sparse
logical matrix fails


Follow-up Comment #2:

Confirmed.  This is actually a regression that happened sometime between 3.2.4
and 3.4.3.  Even in 3.2.4 the behavior isn't totally perfect because the
return value j should be a sparse matrix.

3.2.4 example code:

i = Compressed Column Sparse (rows = 1, cols = 1, nnz = 1 [1e+02%])

  (1, 1) ->  1
j =  1
