Misleading example in debounce docs

[optimized-riyan]

In the debouce example in the docs: debounce, the example uses the interval() function as the durationSelector.

import { fromEvent, scan, debounce, interval } from 'rxjs';

const clicks = fromEvent(document, 'click');
const result = clicks.pipe(
  scan(i => ++i, 1),
  debounce(i => interval(200 * i)) // issue lies here
);
result.subscribe(x => console.log(x));

But as per my knowledge, on every new emission from clicks pipe, debounce will resubscribe the duration selector and since that is a cold observable, the interval will be a new one. However since only the first emission matters, we should be using the timer function right?
While I was trying to understand debounce this example made me scratch my head a lot. I hope fixing this will help newbies out.
