Block templates not respecting "template_lock" when using generateblocks blocks

[lucspe]

Description

I am setting up block templates for custom post types, as described here in the handbook: https://developer.wordpress.org/block-editor/reference-guides/block-api/block-templates/

When I use core blocks in the template and the 'template_lock' argument is set to all, blocks cannot be moved, deleted or new ones added. However, when I use generateblocks blocks in the template and the 'template_lock' argument is set to all, it still allows to move and add blocks.

Steps to reproduce

Assign a block template to to a post type (in the example, to 'post'):

<?php
function ls_register_template() {
    $post_type_object = get_post_type_object( 'post' );
    $post_type_object->template      = $block_template;
    $post_type_object->template_lock = 'all';
}
add_action( 'init', 'ls_register_template' );

example of block_template with core blocks:

$block_template = [
  [
    'core/group',
    [],
    [
      [
        'core/heading',
        [
          'level'   => 2,
          'content' => 'Example Block Template',
        ]
      ],
      [
        'core/paragraph',
        [
          'content' => 'Lorem ipsum dolor sit amet labore cras venenatis.',
        ]
      ],
      [
        'core/columns',
        [],
        [
          [
            'core/column',
            [],
            [
              [
                'core/heading',
                [
                  'level'   => 3,
                  'content' => 'Sub Heading 1',
                ]
              ],
              [
                'core/paragraph',
                [
                  'content' => 'Lorem ipsum dolor sit amet id erat aliquet diam ullamcorper tempus massa eleifend vivamus.',
                ]
              ],
            ]
          ],
          [
            'core/column',
            [],
            [
              [
                'core/heading',
                [
                  'level'   => 3,
                  'content' => 'Sub Heading 2',
                ]
              ],
              [
                'core/paragraph',
                [
                  'content' => 'Morbi augue cursus quam pulvinar eget volutpat suspendisse dictumst mattis id.',
                ]
              ],
            ]
          ],
        ],
      ],
    ]
  ]
];

example of block_template with generateblocks blocks:

$block_template = [
		[
			'generateblocks/container',
			[
				'tagName'   => 'h2',
				'isDynamic' => true,
			],
			[
				[
					'generateblocks/grid',
					[
						'columns'             => 2,
						'isDynamic'           => true,
						'verticalAlignment'   => 'flex-start',
						'horizontalAlignment' => 'center',
					],
					[
						[
							'generateblocks/container',
							[
								'isGrid'      => true,
								'width'       => 50,
								'widthTablet' => 90,
								'widthMobile' => 100,
								'isDynamic'   => true,
							],
							[
								[
									'generateblocks/headline',
									[
										'element' => 'h2',
										'placeholder' => 'Lorem ipsum dolor sit amet, consectetur adipiscing elit.',
									],
								]
							]
						],
						[
							'generateblocks/container',
							[
								'isGrid'      => true,
								'width'       => 50,
								'widthTablet' => 100,
								'widthMobile' => 100,
								'isDynamic'   => true,
							],
							[
								[
									'generateblocks/headline',
									[
										'element' => 'p',
										'placeholder' => 'Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Aenean commodo ligula eget dolor. ',
									],
								]
							]
						],
					],
				],
			]
		],
	];

Expected behavior

I was expecting blocks in the template to be locked when using generateblocks blocks, as it happens with core blocks.

Actual behavior

Generateblocks blocks do not respect the 'template_lock'

p.s.: $block_template is declared inside the function, I have put it in the message separately only for clarity..

We have a new filter in 1.7.0 (https://github.com/tomusborne/generateblocks/tree/release/1.7.0) that might fix this: generateblocks.editor.containerTemplateLock

By default our Container block has templateLock set to false, but this filter opens it up to changes.
