Description

When you change the default post type archive title, you can see it works when on a post type archive page, but there's no effect on the content displayed by the breadcrump for a single post.

Without changing the post type archive title :

• archive page : Home > Events archive
• single page : Home > Events archive > Term name > Post title

When using the post_type_archive_title hook to rename the post type archive title :

• archive page : Home > Events
• single page : Home > Events archive > Term name > Post title

I have used the following function to rename the post type archive title

function rename_archive_title( string $title ): string {
	$post_type        = get_query_var( 'post_type' );
	$post_type_object = get_post_type_object( $post_type );

	return $post_type_object->labels->name ?? $title;
}
add_filter( 'post_type_archive_title', __NAMESPACE__ . '\rename_archive_title', 10 );

Step-by-step reproduction instructions

1. Change the post type archive title using the post_type_archive_title filter hook
2. See that it works on the breadcrumb displayed on the archive page
3. See that it has no effect on the breadcrumb displayed on the single page
