A component with a nested `Inspectable` field causes a panic when expanded

[tgecho]

#[derive(Component, Inspectable, Debug)]
pub struct Behavior {
    actor: Entity,
    state: BehaviorState,
}

#[derive(Inspectable, PartialEq, Eq, Debug)]
pub enum BehaviorState {
    Inactive,
    Running,
    Succeeded,
    Failed,
}

When I try to expand the Behavior component in the inspector pane, it crashes with

This works fine if I use the enum as a component directly. It also works as is in bevy-inspector-egui.

[jakobhellermann]

The panic seems to happen when doing something like

world.resource_scope(|res: Mut<Resource>, world| {
  world.insert_resource(Resource::default());
});

but I'm not sure on which resource.

The panic message could really use some detail (https://github.com/bevyengine/bevy/issues/5365).
