title: Visual Studio Code intellisence doesn't show parameters for wrapper
body: <p>For example I have simple function:</p>
  
  <pre><code>def foo(a):
      '''
      Some function.
      a : int
      '''
      print(a+10)
  </code></pre>
  
  <p>It works as I expected - when I put mouse over the function I can see useful help:<a href="https://i.stack.imgur.com/lykzo.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/lykzo.png" alt="enter image description here"></a></p>
  
  <p>But if I use wrapper for it this useful info about function parameters is lost:</p>
  
  <pre><code>def simple_decorator(f):
      def inner(*args, **kwargs):
          '''
          Simple decorator
          '''
          res = f(*args, **kwargs)
          print('Wrapped')
          return res
      return inner
  
  @simple_decorator
  def foo(a):
      '''
      Some function.
      a : int
      '''
      print(a+10)
  </code></pre>

  <p><strong>BUT! I can see info using Ctrl + mouse over function:</strong></p>

  <p>This way still can't help on showing parameters of function - when I add parenthesis I see only <code>*args, **kwargs</code> again.
  I also tried <code>from functools import wraps</code> it doesn't work too.</p>
  
  <p><strong>Is it possible to make intellisence works correctly, showing parameters of wrapped function? Or maybe show always both of them, as on Ctrl+Mouse?</strong></p>
  
  <p>P.S. I found a lot of closed issues on GitHub but still can't figure out hoqw to solve it. For example:
