Fullscreen / AltScreen does not take the full screen - there seems to be a maximum height

[jbcpollak]

In AltScreen mode, I was expecting huh to display as much of the form as would fit on screen and be continuously responsive to changing sizes of the terminal window. If the terminal window is larger than the form, I would expect the rest of the window to be empty.

Using the main branch of Huh, I modified the scroll example to be:

func main() {
    form := huh.NewForm(
        huh.NewGroup(
            huh.NewInput().Title("First"),
            huh.NewInput().Title("Second"),
            huh.NewInput().Title("Third"),
            huh.NewInput().Title("Fourth"),
            huh.NewInput().Title("Fifth"),
            huh.NewInput().Title("Sixth"),
            huh.NewInput().Title("Seventh"),
            huh.NewInput().Title("Eigth"),
            huh.NewInput().Title("Nineth"),
            huh.NewInput().Title("Tenth"),
        ),
    ).WithProgramOptions(tea.WithAltScreen())
    form.Run()

When the terminal is less than the maximum height of the form, everything is fine and it scrolls normally.

If I expand the terminal, I see the following:

I would have expected the form to expand to fill the screen.

If I shrink and the re-expand the terminal slowly, I can see more of the form, but not as much as could fit:

The behavior seems to be inconsistent and not as I would intuitively expect.
