See the attached gif. I have some C++ code with the code folded. When I go to (right mouse click)>Refactor>Rename Symbol Under Cursor, it's as though the editor is pointing to all references of that symbol by visible line numbers, and not "real" line numbers.

(I have not tried on a new version of Qt Creator because I had to downgrade when the new version increased my Debug runtime to the point of where it was unusable)
