JS error for Select option with number value

[grappler]

When using these two configurations I get an JS error in the console: Uncaught TypeError: data.value.split is not a function

[
	'label'   => esc_html__( 'Zoom', 'static-map' ),
	'attr'    => 'zoom',
	'type'    => 'select',
	'options' => range( 1, 22 ),
],
[
	'label'   => esc_html__( 'Zoom', 'static-map' ),
	'attr'    => 'zoom',
	'type'    => 'select',
	'options' => array_combine( range( 0, 22 ), range( 0, 22 ) ),
],

The reason for this is that the data.value has a typeof number instead of string in these cases.

If I change the code to the following it works fine.

[
	'label'   => esc_html__( 'Zoom', 'static-map' ),
	'attr'    => 'zoom',
	'type'    => 'select',
	'options' => array_combine( range( 1, 22 ), range( 1, 22 ) ),
],
