How to find where title is overridden?

Question

1C-Bitrix

Hello.

I can't change the title on the news page.
In component_epilog.php I set the desired title

$APPLICATION->SetPageProperty("title", "То что хочу видеть");

, but the old title is still displayed on the page.
On the news page, 1 complex component is called bitrix:news, in detail.php there is also only one component. bitrix:news.detail
If at the end of component_epilog.php I break the code execution

$APPLICATION->SetPageProperty("title", "То что хочу видеть");
die();

That title takes the value I need if the code is interrupted after calling the component in detail.php:

...
...
    ),
    $component
  );
    die();

, then my title will be overridden.

Well so the complex component also redefines.
Surely he has a parameter that disables this behavior - look.
But it's best not to use it. What in general can force to use complex components? Complex components are an evil which must be avoided by all available means.
