Bug Kate - rename "Save As" doesn't Update name in file list if extensions shortened (e.g. .cpp to .c)

I need someone to confirm a bug with the Kate documents list. If you have a file saved, e.g. main.cpp and then "Save As" main.c the window continues to show main.cpp. Same if you have file.txt and "Save As" file.t, the name in the document list remains file.txt even though you are editing file.t now. If you can confirm, I'll write the bug up. -- David C. Rankin, J.D.,P.E.
