Make GTK Entry box smaller

I am trying to make a GUI program in Julia using Gtk. My program includes a large number of GtkEntry boxes. However, I am running into space issues because the Entry boxes have a lot of internal padding around the actual characters. I would like to reduce, at least, the top and bottom whitespace. I have tried to use the setproperty!() function to change the height-request value, but that seems to be only able to make the box bigger, not smaller. Additionally, the margin, margin-top, etc. fields are all set to 0 by default. Again, I can make them bigger but not smaller.

Is this possible to fix? I have included below a minimal working example, a screenshot, and a Julia REPL output displaying the available properties.

Edit: I have also tried using a css file (test.css) with the contents

entry {
  margin-top: 0;
  margin-bottom: 0;
  padding-top: 0;
  padding-bottom: 0;
}

Julia 0.6.0 code:

using Gtk

win = GtkWindow("Example")

sb = GtkGrid()
function sb_entry(label)
    frame = GtkFrame(label)
    entry = GtkEntry()
    setproperty!(entry, :input_purpose, 2)
    push!(frame, entry)
    return frame
end
sb_rows = sb_entry("rows")
sb_cols = sb_entry("cols")
sb_row_off = sb_entry("row off")
sb_col_off = sb_entry("col off")
sb[1,1] = sb_rows
sb[2,1] = sb_cols
sb[1,2] = sb_row_off
sb[2,2] = sb_col_off
setproperty!(sb, :column_homogeneous, true)
setproperty!(sb, :column_spacing, 5)
setproperty!(sb, :row_spacing, 5)

push!(win, sb)

### begin edit (css)

screen   = Gtk.GAccessor.screen(win)
provider = GtkCssProviderLeaf(filename="/path/to/test.css")

ccall((:gtk_style_context_add_provider_for_screen, Gtk.libgtk), Void,
        (Ptr{Void}, Ptr{GObject}, Cuint),
        screen, provider, 1)

### end edit (css)

showall(win)

if !isinteractive()
    c = Condition()
    signal_connect(win, :destroy) do widget
        notify(c)
    end
    wait(c)
end

entry { min-height: 0px; } allows it to be as small as possible. Adjust size as required.
