Controlling bubbles.Help FullHelpView rendering widths

[DaltonSW]

Howdy, I'm looking to override the disable the built-in Help for a list and render out my own using the help bubble. I'm defining each of my bindings, adding them to the ShowFullHelp() method in 3 columns, but then find that the spacing between the columns is inconsistent

If I add a "full separator", it only seems to show up between the first and second columns

I've tried setting the Width as well, and no dice. The only thing I've been able to make kinda work is by adding spaces manually to the end of each binding's descriptions

Any insight or help would be greatly appreciated!

Here's my keymap definition snippet

type styleKeymap struct {
	Up    key.Binding
	Down  key.Binding
	Left  key.Binding
	Right key.Binding

	Select key.Binding
	Quit   key.Binding
}

func (k styleKeymap) ShortHelp() []key.Binding {
	return []key.Binding{k.Up, k.Down, k.Select, k.Quit}
}

func (k styleKeymap) FullHelp() [][]key.Binding {
	return [][]key.Binding{
		{k.Up, k.Down}, //, k.Select, k.Quit},
		{k.Left, k.Right},
		{k.Select, k.Quit},
	}
}

func newStyleKeymap() styleKeymap {
	return styleKeymap{
		Up: key.NewBinding(
			key.WithKeys("shift+tab", "up"),
			key.WithHelp("ShTab/↑", "Up"),
		),
		Down: key.NewBinding(
			key.WithKeys("tab", "down"),
			key.WithHelp("tab/↓", "Down"),
		),

		Left: key.NewBinding(
			key.WithKeys("left", "h"),
			key.WithHelp("h/←", "-1"),
		),
		Right: key.NewBinding(
			key.WithKeys("right", "l"),
			key.WithHelp("l/→", "+1"),
		),
		Select: key.NewBinding(
			key.WithKeys("enter"),
			key.WithHelp("enter", "Toggle"),
		),
		Quit: key.NewBinding(
			key.WithKeys("esc", "ctrl+c"),
			key.WithHelp("esc", "Quit"),
		),
	}
}
