Labwc: menu items in the bottom are cut out of the page when there are too many items

[archisman-panigrahi]

I have a lot of items in my Accessories, and they don't fit within the screen. In X11, I can scroll through the menu to access the items in the bottom.

In labwc, there is no way to scroll, and the menu items which do not fit inside the screen are not shown and there is no way to access them.
While the issue may not show up in a huge monitor (with space for a lot of icons), it becomes a problem in systems with smaller screens (e.g. a regular laptop sized screen, or even smaller screens used by cool RPi projects), and with touch screen systems without a keyboard (it is painful to type name of apps in touch keyboard every time you need to open an app).

It would be nice to have a scrollbar in the menu in labwc.

Menus never have scrollbars, but they can have arrows top and bottom to allow the content to be scrolled. I'll see if I can add this.
