How come Laser requires re-render but Eraser doesn't?

	export class Laser extends Brush {
	pathCreated = (e: PathEvent): void => {
	setTimeout(() => {
	this.baseCanvas.remove(e.path);
	this.baseCanvas.requestRenderAll();
	}, 1000);
	};

Lines 163 to 173 in fe6fdc3

	export class Eraser extends Brush {
	pathCreated = (e: PathEvent): void => {
	const path = fabric.util.object.clone(e.path);
	this.baseCanvas.remove(e.path);
	const objects = this.baseCanvas
	.getObjects()
	.filter((object) => object.intersectsWithObject(path));
	if (!objects.length) return;
	this.baseCanvas.remove(...objects);
	this.history.remove(objects);
	};

Is it because Eraser path operations are done immediately after creating the stroke, so that the render happens slightly after the invocation of the function? If so, is this guaranteed by fabric (I doubt it) or just lucky?

(Replacing Eraser with Pen in this question also raises a valid question, but the answer to that question is that you don't do anything worthy of re-render.)
