Quick fix popup sometimes does not show name of header to include

1. Have two simple instantiations in a source file without including the needed headers:

   QMessageBox mb;
   QLabel l;
   

2. Move the cursor to the word "QLabel" and press Alt+Enter.
   You'll see a popup offering to "Add #include <QLabel>".
3. Press Escape.
4. Move the cursor to the word "QMessageBox" and press Alt+Enter.
   You'll see a popup offering to "Add #include <QMessageBox>".
5. Press Enter.
   The said header line will be inserted.
6. Move the cursor to the word "QLabel" and press Alt+Enter.
   You'll see a popup offering to "#include Header File".

Shouldn't the same popup be shown in steps 2 and 6?
