label.
The `y_align` argument determines how the *entire label* is aligned within
its available space, not how the text is aligned within the label. So when
you set the label to take up all itsavailable space, `y_align` has no
effect.
You can do:
box.add(label, {y_fill: false, y_align: St.Align.MIDDLE})
which will make the label just as big as it needs to be to display its
contents, and positions the label vertically in its BoxLayout cell (try
doing `box.style = 'border: 1px solid blue'` and `label.style = 'border:
1px solid red'` to see how the label and boxlayout are positioned).
Second problem: I need a multi-line label, to show a long string. But all I
