issue using rwmb_frontend_dashboard_delete_action filter to remove delete icon

For whatever reason, the delete icon on the frontend dashboard is being displayed, even if a user does not have permission to delete a post type. For example, if the post type is workplace and the permission for delete_workplaces is not granted, the delete icon is still displayed.

To get around this we are using the rwmb_frontend_dashboard_delete_action as follows:

add_filter( 'rwmb_frontend_dashboard_delete_action', 'fix_frontend_delete_button', 20, 2 );
function fix_frontend_delete_button ( $show_delete, $post_id ){
	$post_type = get_post_type( $post_id ); //workplace
	if ( !current_user_can( 'delete_'.$post_type.'s' ) ) {
		$show_delete = false;
	}
}

However, if $show_delete returns false then a JS error is being thrown in the console:

frontend-submission.js?ver=4.4.0:1 Uncaught ReferenceError: mbFrontendForm is not defined
    at frontend-submission.js?ver=4.4.0:1:22
    at frontend-submission.js?ver=4.4.0:1:2579

After looking at how the rwmb_frontend_dashboard_delete_action filter is being used in DashboardRenderer.php:

$delete_action = true;
// Filter the delete action
$delete_action = apply_filters( 'rwmb_frontend_dashboard_delete_action', $delete_action, get_the_ID() );
if ( $delete_action ) {
	echo do_shortcode( '[mb_frontend_form id="' . $this->edit_page_atts['id'] . '" post_id="' . get_the_ID() . '" ajax="true" allow_delete="true" force_delete="' . $atts['force_delete'] . '" only_delete="true" delete_button="<img src=\'' . MBFS_URL . 'assets/trash.svg\'>"]' );
}

it seems that the mb_frontend_form shortcode must be present. We have found a temp work-around by adding:

else {
	echo do_shortcode( '[mb_frontend_form id="' . $this->edit_page_atts['id'] . '" post_id="' . get_the_ID() . '" ajax="true" allow_delete="false" only_delete="true" delete_button=" "]' );
}

But it seems there is a deeper issue that needs to be addressed here.
Any ideas on how this can be properly addressed?
