Style `max_size` does not work

[CatThingy]

Bevy version

0.10.0

What you did

use bevy::prelude::*;
fn main() {
    App::new()
        .add_plugins(DefaultPlugins)
        .add_startup_system(init)
        .run()
}

fn init(mut cmd: Commands) {
    cmd.spawn(Camera2dBundle::default());
    cmd.spawn(NodeBundle {
        style: Style {
            size: Size {
                width: Val::Percent(50.0),
                height: Val::Percent(100.0),
            },
            max_size: Size {
                width: Val::Px(100.0),
                height: Val::Percent(100.0),
            },
            ..default()
        },
        background_color: BackgroundColor(Color::NAVY),
        ..default()
    });
}

What went wrong

I expected the UI node (in navy) to have a maximum width of 100px. This was the result in Bevy 0.9
However, the UI node always has a width of 50% of the window size.

Additional information

I bisected this to the update to Taffy 0.3; however, I was unable to reproduce this with just Taffy:

use taffy::prelude::*;

fn main() {
    let mut taffy = Taffy::new();

    let body = taffy
        .new_leaf(Style {
            size: Size {
                width: percent(50.0),
                height: Dimension::Auto,
            },
            max_size: Size {
                width: points(100.0),
                height: Dimension::Auto,
            },
            ..Default::default()
        })
        .unwrap();

    let root = taffy
        .new_with_children(
            Style {
                size: Size {
                    width: points(1000.0),
                    height: points(600.0),
                },
                ..Default::default()
            },
            &[body],
        )
        .unwrap();

    taffy.compute_layout(root, Size::MAX_CONTENT).unwrap();

    assert_eq!(100.0, taffy.layout(body).unwrap().size.width);
}

I believe this would be fixed by #7948. Would you mind checking?

[CatThingy]

Yep, that fixes it.
