[BUG] table.add_section does not draw a line / appear to do anything

[adamcunnington-mlg]

• [ x ] I've checked docs and closed issues for possible solutions.
• [ x ] I can't find my issue in the FAQ.

Describe the bug
I'm not sure if this is expected or not but rich.table.Table(..., leading=1) (presumably any number) combined with rich.table.Table.add_section() causes the section to not render.

Minimal reproduction:

def test():
    from rich import table, console
    t = table.Table(title="Preset Lint Violations", title_justify="left", leading=1)
    t.add_column("Foo", style="magenta", no_wrap=True)
    t.add_column("Bar", style="cyan")
    t.add_row("Before Section", "Bar")
    t.add_row("Before Section", "Bar")
    t.add_section()
    t.add_row("After Section", "Bar")
    t.add_row("After Section", "Bar")
    console.Console().print(t)

test()

If I don't use leading=1, looks as expected:

If I do use it, it looks like this:

If this is expected behaviour, I think it's weird/bad/confusing. I expect leading=1 to effectively give me row padding but not to stop sections rendering.

Platform
I am using Windows Terminal + WSL running Ubuntu 22.04 so maybe it's that combination of tooling that's leading to a visual nuance?
