Problem Description

Not all arguments are being printed, when a docstring is generated under a function, that has many arguments. Furthermore, other standard ways don't work at all - right click menu option Generate docstring is inactive, and Ctrl+Alt+D just moves the cursor up to the argument, which gets printed first, when using the """ method (in my case it's default_config_path argument). I use standalone Spyder (not with Anaconda).

What steps reproduce the problem?

Type """ in the first line of function
Click Generate docstring popup, when it appears
See the broken docstring

What is the expected output? What do you see instead?

I expected every stated argument to appear in the docstring, but it only prints 12 of them (there are 22 in total), and also the alignment is broken (docstring's body drives off to the right). It only happens to functions with many arguments:
