Here's an example where the parent of an attribute in a chained attribute is wrong, pointing to a following attribute instead.

#!python

from astroid import parse
module = parse('''
class Tags:
     def extend(self): return 42
class Removed:
     def __init__(self):
          self.tags = Tags()

removed = Removed()
removed.tags.extend()
''')
expr = module.body[-1]
callfunc = expr.value
print("callfunc", callfunc)
print("parent of callfunc", callfunc.parent)
print("func of callfunc", callfunc.func)
print("parent of func of callfunc", callfunc.func.parent)
print("expr of callfunc.func", callfunc.func.expr)
print("parent of expr of callfunc.func", callfunc.func.expr.parent)  # This should be the Name, instead it is extend

from ast import parse
module = parse('''
class Tags:
     def extend(self): return 42
class Removed:
     def __init__(self):
          self.tags = Tags()

removed = Removed()
removed.tags.extend()
''')
expr = module.body[-1]
callfunc = expr.value
print("callfunc", callfunc)
print("func of callfunc", callfunc.func.attr)
print("expr of callfunc", callfunc.func.value.attr)
print("expr of expr of callfunc", callfunc.func.value.value)
