[Outliner]: `updateGroup` accepts `_delta` but never applies it? dead code?

[ShaMan123]

Describe the bug 📝

_delta is never referenced in the function, it seems like dead code from pre-group era.
The outliner logic changes the state.map attr and that is used by updateGroup:

engine_components/packages/front/src/fragments/Outliner/index.ts

Lines 455 to 470 in 1d8ca36

	private async updateGroup(name: string, _delta?: OBC.ModelIdMap) {
	const state = this.ensureGroup(name);
	if (!this.world) return;
	const renderer = this.getRenderer();
	const pass = renderer.postproduction.outlinePass;
	// Make sure the pass knows about this group (palette + material +
	// container). The Outliner's ensureGroup only tracks selection state.
	if (!pass.hasGroup(name)) pass.addGroup(name);
	if (name === DEFAULT_GROUP && this.outlinePositions) {
	await this.updatePoints();
	}
	const fragments = this.components.get(OBC.FragmentsManager);
	const map = state.map;
