GtkMenu’s own keynav code, which actually bothers to account for the
layout of items, only happens if columns > 1. So, adding items to 1
column using a reverse loop meant they were placed in the Menu’s list of
children in that order, and because we only have 1 column, Menu passes
keynav up to MenuShell, which doesn’t adjust for the items’ positions.
‘Fix’ that here by adding items in the same order they’ll have when laid
out in the Menu, so keynav does what you’d expect, not the opposite. For
that, it’s simpler just to use gtk_container_add().
Let’s presume users are using add(), attach() with a non-inverted loop,
or attach() with arguments that create 2+ columns and so GtkMenu keynav.
Ditch two items that were white and so weren’t visible on our standard
theme anyway, and use the new space to test extra grid-mode properties.
Note that if we do this then, as before, we set the ListStore on the
ComboBox before appending to it, that produced runtime warnings like:
Gtk-CRITICAL **: gtk_menu_attach: assertion 'left_attach < right_attach' failed
I didn’t look into that yet, but it may indicate that attaching items
vs. recognising their spans don’t occur in the correct order. For the
purposes of testing this, I just create the CB after filling its model.
The ComboBoxes were initially empty, rather than reflecting the initial
values of the properties. The CheckButtons were only correct by chance.
Fix this by setting the initial values on the widgets and binding them
to the properties using SYNC_CREATE, so the two are always synced up.

Just to test tooltips in all cases; what was already here
should have been sufficient, but this doesn't hurt.
While here, also add some instructive placeholder text.

Add a test for exporting a handle. There are no GTK+ API for this, but
only per backend GDK API, and so far only Wayland is supported. There
is a private GdkWindow API but it's not exposed externally.

The CSS was targeting node GtkFrame, which is wrong: it is called frame.
This commit also assumes the interesting padding is that between the
border and the child widget, not the padding around the entire Frame.
Some additional hoops must be jumped through to preserve padding values
not being changed in either callback. However, the way this is done
means I must set the initial paddings to 0, which simplifies main().
The :label-widget is drawn before the child, so put the controls that
set the alignment of the :label-widget before those that pad the child.
We set (horizontal|vertical) padding, not "[xy]thickness". Also change
to "label [xy]align" & use grid spacing, not spaces at end of Labels.
I added a new test function, but didn't actually use it.
No wonder I couldn't reproduce the lifecycle issues with
drag widgets that firefox is experiencing.
