How nested loops with unique keys behaves?

vue-core

Hi there, I have a question regarding how the DOM will be updated on nested loops.
The docs says what each component has an isolated scope so…
Suppose I have a loop in ComponentLevel1 which renders a collection of ComponentLevel2 and inside the lasts we have loops rendering ComponentLevel3 always having unique keys like i show below…

ComponentLevel1
	|-> ComponentLevel2
		|-> ComponentLevel3
	|-> ComponentLevel2
		|-> ComponentLevel3
		|-> ComponentLevel3
	|-> ComponentLevel2
		|-> ComponentLevel3

If I change only the unique keys in the Level1? All the child components in the inner levels will be re rendered as well?
Or ill have to change the unique keys in all the levels?
Thanks, Ill appreciate your knowledge in this.
