False positive E1126 when using np.newaxis

[NeilGirdhar]

Steps to reproduce

import numpy as np

solution = np.array([2.1, 1.3], dtype=np.float32)
input_size = solution.shape[0]

times = [1, 2, 3]
inputs = [(time, np.random.normal(size=input_size))
          for time in times]
targets = [(time, np.dot(solution, input_)[np.newaxis])
           for time, input_ in inputs]

Current behavior

 E1126: Sequence index is not an int, slice, or instance with __index__ (invalid-sequence-index)
