Breaks elementor editor on specfic pages

woo-pelecard-gateway/includes/Plugin.php

Original (broken, triggers redirect in Elementor when editing the page):

	public function frame_buster_snippet() {
		// Honor merchant opt-out via gateway setting.
		$gateway = Gateway::instance();
		if ( 'yes' !== $gateway->get_option( 'frame_buster', 'yes' ) ) {
			return;
		}

		// Limit scope to checkout-related pages so non-payment iframes on the
		// site (e.g. embeds inside product descriptions) are untouched.
		if ( ! function_exists( 'is_checkout' ) ) {
			return;
		}

		$relevant = is_checkout()
			|| is_cart()
			|| is_wc_endpoint_url( 'order-received' )
			|| is_wc_endpoint_url( 'order-pay' )
			|| is_add_payment_method_page();

		if ( ! $relevant ) {
			return;
		}

		?>
		<script>
		(function () {
			try {
				if ( window.top !== window.self
					&& window.top.location.hostname === window.location.hostname ) {
					window.top.location.href = window.location.href;
				}
			} catch ( e ) {}
		})();
		</script>
		<?php
	}

Fixed (added check for Elementor):

public function frame_buster_snippet() {
    // Honor merchant opt-out via gateway setting.
    $gateway = Gateway::instance();
    if ( 'yes' !== $gateway->get_option( 'frame_buster', 'yes' ) ) {
        return;
    }

    // Limit scope to checkout-related pages so non-payment iframes on the
    // site (e.g. embeds inside product descriptions) are untouched.
    if ( ! function_exists( 'is_checkout' ) ) {
        return;
    }

    $relevant = is_checkout()
        || is_cart()
        || is_wc_endpoint_url( 'order-received' )
        || is_wc_endpoint_url( 'order-pay' )
        || is_add_payment_method_page();

    if ( ! $relevant ) {
        return;
    }

    if(!(class_exists('\Elementor\Plugin') && (\Elementor\Plugin::$instance->editor->is_edit_mode() || \Elementor\Plugin::$instance->preview->is_preview_mode()))) {
    ?>
    <script>
    (function () {
        try {
            if ( window.top !== window.self
                && window.top.location.hostname === window.location.hostname ) {
                window.top.location.href = window.location.href;
            }
        } catch ( e ) {}
    })();
    </script>
    <?php
    }
}

This fixed the problem for us, but not sure if it other page builders might have same problem.
