get_bloginfo argument in admin-header.php

Please, take a look at the following line in /wp-admin/admin-header.php:

$admin_title = get_bloginfo( 'name' );

The value of name is fetched with the purpose of display in the title attribute, which most of browsers show as a page tab label.

Function get_bloginfo has the second argument, with default value ‘raw’. Alternative value can be ‘display’:

$admin_title = get_bloginfo( 'name', 'display' );

which seems more applicable in this case.

Similar problem is in /wp-admin/customize.php:

echo sprintf( __( 'You are customizing %s' ), '<strong class="theme-name site-title">' . get_bloginfo( 'name' ) . '</strong>' );

Is this an overlook, or there is a deep reason for this? It does not make difference in the most of the cases, but ‘display’ argument provides additional filters inside get_bloginfo, which allow to customize the value, while ‘raw’ argument does not.

Thank you very much.
