Filter: bcn_breadcrumb_template missing

According to the documentation, there should be a filter named bcn_breadcrumb_template. I found that my filter function was not being executed, and after looking at the plugin function that calls this filter, I see it is not being run. Since this filter was recently introduced in v4.4, I assume it was left out in error.

/**
	 * Function to set the internal breadcrumb template
	 *
	 * @param string $template the template to use durring assebly
	 */
	public function set_template($template)
	{
		//Assign the breadcrumb template
		$this->template = wp_kses($template, $this->allowed_html);
	}
