Python FP when using multiple decorators on class function

[Anthchirp]

In https://lgtm.com/projects/g/dials/dials/snapshot/5c386da2f97d98b7ec80e34cec0cbf894fce6a36/files/util/filter_reflections.py?sort=name&dir=ASC&mode=heatmap#L288 a function is defined as:

class X:
  @staticmethod
  @seconddecorator
  def function(parameter):

Due to the presence of the decorator @seconddecorator the type of parameter is inferred to be instances of X. This is of course not true due to the @staticmethod decorator being present.
This can then lead to false positives on operations on parameter further down the line.
