Split Container does not respect item's Visible status

Describe the bug

When an item in a Split container is hidden, the split should should act is if there is nothing there for that item. Neither the Layout nor the MinSize function examine the Visible status of the items.

How to reproduce

1. Run the attached code, which is a Split container with buttons on the left and a Label on the right
2. Drag the slider around to verify it works properly. Note that if you drag the slider right to the MinSize of the Label, the pointer moves, but the slider does not. While still holding the click, drag the slider back to the left and you can see that the pointer and the slider handle become out of sync.
3. Click the Hide button
4. Drag the slider around. Note that it behaves exactly the same, but with the label hidden. I would expect that with the label hidden, I could drag the slider all the way to the right edge of the window

func main() {
	myApp := app.New()
	myWindow := myApp.NewWindow("Form Layout")

	label := widget.NewLabel("I am a longish label that just sits here")

	buttons := container.NewVBox(
		widget.NewButton("Show", func() {label.Show()}),
		widget.NewButton("Hide", func() {label.Hide()}),
	)

	c := container.NewHSplit(buttons, label)

	myWindow.SetContent(c)
	myWindow.Resize(fyne.NewSize(500, 300))
	myWindow.ShowAndRun()
}
