GtkNotebook built-in popup menu listing tabs doesn't use tab label text for the last tab
Steps to reproduce
glade-previewer --filename notebook.ui
- right click on tabs, popup of list of tabs appears
- the popup lists the names of the tabs, except for the last tab, which is always "Page X", 3 in this case
Current behavior
Last tab gets generic "Page X" name
Expected outcome
Same behaviour for all tabs
Version information
