Autocomplete in documentation comments no longer working

[cyberbit]

I don't know what version this started happening in, but I think it traces back to when the integration of php-integrator happened. When typing a docblock, with the cursor at the location with the vertical bar below, I would be recommended a variety of autocompletions like \Illuminate\Http\Request and similar.

/**
 * This is a function
 * 
 * @return Req|
 */
public function showForm() {
    // ...
}

Now, I don't get any autocomplete in comments relating to PHP classes. Autocompletion works elsewhere in function bodies and declarations.
