External scripts (with `src`) also put DOM building to pause while the script is loading and executing. So `DOMContentLoaded` waits for external scripts as well.
The only exception are external scripts with `async` and `defer` attributes. They tell the browser to continue processing without waiting for the scripts. So the user can see the page before scripts finish loading, good for performance.
