How can I change the font size of a label in Gtk4.jl?

I have the following code:

using Gtk4

win = GtkWindow("My First Gtk4.jl Program", 400, 200)
hbox = GtkBox(:h)  # :h makes a horizontal layout, :v a vertical layout
push!(win, hbox)
label = GtkLabel("  Power:")
value = GtkLabel("  22.4")
push!(hbox, label)
push!(hbox, value)
hbox.spacing = 10
hbox.homogeneous = true

show(win)
nothing

and the text is way too small…

OK, this works:

    win = GtkWindow("My First Gtk4.jl Program", 400, 200)
    css = """
    button {
        font-size: 3.0em;
    }
    """
    cssProvider = GtkCssProvider(css)
    push!(Gtk4.display(win), cssProvider)

    hbox = GtkBox(:h)  # :h makes a horizontal layout, :v a vertical layout
    push!(win, hbox)

    label = GtkButton("  Power:")
    value = GtkButton("  22.4")
    push!(hbox, label)
    push!(hbox, value)
    hbox.spacing = 10
    hbox.homogeneous = true
    show(win)
    nothing

But it does NOT work when I use GtkLabel instead of GtkButton…

Guess that’s a bug, then…

This works:

win = GtkWindow("My First Gtk4.jl Program", 400, 200)
css = """
label {
    font-size: 3.0em;
}
"""
cssProvider = GtkCssProvider(css)
push!(Gtk4.display(win), cssProvider)

hbox = GtkBox(:h)  # :h makes a horizontal layout, :v a vertical layout
push!(win, hbox)

label = GtkLabel("  Power:")
value = GtkLabel("  22.4")
push!(hbox, label)
push!(hbox, value)
hbox.spacing = 10
hbox.homogeneous = true
show(win)
nothing

Sorry for the noise…
