Does the Drupal error_reporting() check still work?

Problem/Motivation

_drupal_error_handler_real() has this first line:

  if ($error_level & error_reporting()) {

Now look at this PHP documentation page for error control. Relevant portion quoted here:

Warning

Prior to PHP 8.0.0, the error_reporting() called inside the custom error handler always returned 0 if the error was suppressed by the @ operator. As of PHP 8.0.0, it returns the value E_ERROR | E_CORE_ERROR | E_COMPILE_ERROR | E_USER_ERROR | E_RECOVERABLE_ERROR | E_PARSE.

So the if statement above is checking if truthy (aka, not zero). I'm wondering if this is still correct in PHP 8, as the value returned from error_reporting() when errors are suppressed is different, namely it is the value quoted above, which equals 4437.
