Empty lines (containing "") are hidden in List output

Description

I am building an alternative to the watch command watchbind.
I am using the widget List with Listitems.
I am wondering why the example code

	let items = vec![
		ListItem::new("line one"),
		ListItem::new(""),
		ListItem::new("line four"),
	];
	let list = List::new(items)
		.style(Style::default().fg(Color::White))
		.highlight_style(Style::default().fg(Color::Black).bg(Color::White));
	f.render_stateful_widget(list, f.size(), &mut events.state);

does not render the second line, but the state obviously knows about it because I can scroll normally with j and k (which I programmed).

To Reproduce

Expected behavior

All lines should be visible in the output, even the empty lines.

Screenshots

On the left side is the output of watchbind -- git -h, on the right side git -h. As you can see, the empty lines are omitted on the left, which uses the tui List widget.

Environment

• OS: Linux
• Terminal Emulator: kitty
• Crate version: 0.19
• Backend: crossterm

Additional context

I have switched to Table with Rows over List and now all Lines are displayed correctly. It seems like List just ignored empty lines.
