I'm using the amazing wrapt.synchronized decorator, but I've just realized that it breaks the typing signature of the wrapped function (using vscode). I tested it with custom wrapt.decorator function and it works fine. Does someone have a solution?

Example:

import wrapt 

@wrapt.decorator
def pass_through(wrapped, instance, args, kwargs):
    return wrapped(*args, **kwargs)

@pass_through
def function(arg):
    print(arg)

@wrapt.synchronized
def synced_function(arg):
    print(arg)

The function signature:

The synced_function signature:
