Syntax selection menu does not scroll (GTK)

[romuald]

Description

The syntax selection tool (either from the "bottom" UI or the top menu), does not allow user to scroll it.

Steps to reproduce

1. Start Sublime Text in safe mode
2. Click on View > Syntax menu
3. In case the menu is larger than the screen. The UI does not allow to scroll it, and thus elements are not available to select using the mouse (they are using the keyboard but we cannot see what element is selected)

Expected behavior

The menu should be scrollable in some way to allow access to the bottom elements

Actual behavior

The bottom elements aren't visible or accessible

Here is a screenshot

Environment

• Build: 4107 (tested with 4105 and 4094, both also have the issue)
• Operating system and version: Linux 5.10
• [Linux] Desktop Environment and/or Window Manager: i3

Those menus are native OS menus. Shouldn't it be handled by GTK?

@deathaxe I've made a quick test using python / GTK and the menu is scrollable on the same system

I know very little about GTK so maybe there is different kind of menus

Here is my example:

#!/usr/bin/python3

def main():
    from gi import pygtkcompat
    pygtkcompat.enable_gtk(version='3.0')

    import gtk

    menu = gtk.Menu()

    items = [gtk.MenuItem(str(i)) for i in range(80)]

    for item in items:
        menu.append(item)
        item.show()

    menu.connect('hide', gtk.main_quit)
    menu.connect('key-release-event', gtk.main_quit)

    menu.popup(parent_menu_shell=None,
               parent_menu_item=None,
               func=None,
               data=None,
               button=1,
               activate_time=0)

    gtk.main()

if __name__ == '__main__':
    main()
