"No documentation available" error on function if too few arguments

F1 on a function does not work if the arguments does not match the function.

Many times one needs documentation on a function, but if the signature does not match then neither help nor follow function under cursor works.

 Create a normal Console Project, add the lines as shown:

#include <QCoreApplication>

int main(int argc, char *argv[])
{
  QCoreApplication a(argc, argv);
  
  a.addLibraryPath(); // New line

  return a.exec();
}

Click on the addLibraryPath function and press F1: Creator opens the Help Mode page but states "No documentation available"

Expected: Help mode should be on the QCoreApplication::addLibraryPath() function

Also control click on the  function nor the variable name does nothing. 

This is a huge issue from a productivity point.
