What is the purpose of setTimeout?

You didn't explain it in How it works.

setTimeout is used when we want to run a function after a set of time is passed.

I know what setTimeout does, but there is no explicit timeout being set, so what is its purpose in this particular case?

I've just added an explanation to setTimeout in the dev snippet!

tl;dr: The browser automatically scrolls DOM changes into view in response to user interaction.

See 1a1e82e

This is interesting: If your webapp is a fullscreen SPA (no scrolling), then you can remove the setTimeout wrapper!

Which results in a 150-byte snippet, which is very tempting... But it makes tabbed UIs annoying (such as the demo section in the htmz website, so would not be a good impression).

Lines 5 to 7 in 1a1e82e

	// The browser automatically scrolls DOM changes into view in response to user interaction.
	// This delay prevents that, making this is the only case where we don't lean on browser defaults.
	// Remove setTimeout wrapper to allow automatic scrolling.

  ⋯ If your webapp is a fullscreen SPA (no scrolling), then you can remove the setTimeout wrapper ⋯

  Wouldn't it thus break responsiveness?
  In that case, it is interesting to know, but for sure not desired unless unresponsiveness is not an issue and saving 16 bytes is critical.
