    #   Failed test at t/drop-empty-elements.t line 34.
    #     Structures begin differing at:
    #          $got->[0] = 'test (4:9) Warning: blank 'title' element'
    #     $expected->[0] = 'test (7:9) Warning: trimming empty <span>'
    # Looks like you failed 1 test of 2.

#   Failed test 'default constructor warns about empty spans'
#   at t/drop-empty-elements.t line 37.

    #   Failed test at t/drop-empty-elements.t line 46.
    #     Structures begin differing at:

    # Looks like you failed 1 test of 2.

    # Looks like you failed 1 test of 2.

t/drop-empty-elements.t .... 
Dubious, test returned 3 (wstat 768, 0x300)
