Sortable breaks term edit screen UI

[dlh01]

Description of the bug

Adding a sortable group to the edit-term screen causes the drag handler to take up the entire height of the screen, blocking access to other fields and making the handler itself nearly impossible to use.

Steps To Reproduce

Example field definition:

$editorial_board = new Fieldmanager_Group(
	[
		'name'           => 'example_issue_editorial_board',
		'add_more_label' => __( 'Add Group', 'example' ),
		'children'       => [
			'title'   => new Fieldmanager_TextField(
				[
					'label' => __( 'Title', 'example' ),
				],
			),
			'content' => new Fieldmanager_TextArea(
				[
					'label' => __( 'Content', 'example' ),
				],
			),
		],
		'limit'          => 0,
		'sortable'       => true,
	],
);
$editorial_board->add_term_meta_box( __( 'Editorial Board', 'example' ), 'example_magazine_issue' );
