How to remove “Oxygen Visual Editor” from page titles in Oxygen

Oxygen editor pages have “Oxygen Visual Editor” in the titles by default.

Ex.: Oxygen Visual Editor - Sample Page - Oxygen

where the last title part, Oxygen in this case is the site title.

If you have a number of tabs open in your browser you may be looking to remove that so the page titles are compact like this:

Sample Page - Oxygen

This can be done using the following PHP snippet:

add_action( 'init', 'custom_is_show_builder', 1 );
function custom_is_show_builder() {
	if ( isset( $_GET['ct_builder'] ) && $_GET['ct_builder'] ) {
		remove_filter( 'document_title_parts', 'ct_builder_wp_title', 10, 1 );
		
		add_filter( 'document_title_parts', 'custom_builder_wp_title', 10, 1 );
	}	
}

function custom_builder_wp_title( $title ) {
	$title['title'] = ( isset($title['title'] ) ? $title['title'] : '' );
	
	return $title;
}

It can be added using a plugin like Code Snippets.

If you want to have the titles in this format:

O2 - Sample Page - Oxygen

replace

$title['title'] = ( isset($title['title'] ) ? $title['title'] : '' );

in the above with

$title['title'] = ( isset($title['title'] ) ? 'O2 - ' . $title['title'] : '' );
