What you did

Spawned a mesh with the Disabled component, and had another system enable the entity.

use bevy::{color::palettes::tailwind::CYAN_400, ecs::entity_disabling::Disabled, prelude::*};

fn main() {
    App::new()
        .add_plugins(DefaultPlugins)
        .add_systems(Startup, setup)
        .add_systems(Update, toggle_disabled)
        .run();
}

fn toggle_disabled(
    mut query: Query<(Entity, Has<Disabled>), With<Mesh2d>>,
    keyboard: Res<ButtonInput<KeyCode>>,
    mut commands: Commands,
) {
    if keyboard.just_pressed(KeyCode::Space) {
        for (entity, disabled) in &mut query {
            if disabled {
                info!("Enabling entity {:?}", entity);
                commands.entity(entity).remove::<Disabled>();
            } else {
                info!("Disabling entity {:?}", entity);
                commands.entity(entity).insert(Disabled);
            }
        }
    }
}

fn setup(
    mut commands: Commands,
    mut materials: ResMut<Assets<ColorMaterial>>,
    mut meshes: ResMut<Assets<Mesh>>,
) {
    commands.spawn(Camera2d);

    commands.spawn((
        Mesh2d(meshes.add(Rectangle::new(50.0, 50.0))),
        MeshMaterial2d(materials.add(Color::from(CYAN_400))),
        Disabled,
    ));
}

What went wrong

Nothing is rendered, even after toggling Disabled several times.

It does however log the messages correctly.

If I don't add Disabled at spawn, it is rendered like expected:

and it is hidden and shown again when toggling Disabled by pressing Space.

Additional information

I ran into this in an Avian example. It was rendering my immediate-mode debug rendering gizmos for the collider, and the physics entity was still being simulated, but the mesh was not visible. I have not tested if this was working before 0.18.

It also doesn't seem like a problem with required components. I checked, and the entity had a Transform given by Mesh2d even when the entity was spawned as disabled.
