Sort blocks inside layout regions by weight.

my_theme.theme
/**
 * Implements hook_preprocess_HOOK() for layout.html.twig.
 */
function hook_preprocess_layout(&$variables) {
  $layout = $variables['layout'];
  foreach ($layout->getRegionNames() as $region_name) {
    if (array_key_exists($region_name, $variables['content'])) {
      uasort($variables['content'][$region_name], [\Drupal\Component\Utility\SortArray::class, 'sortByWeightProperty']);
    }
  }
}

Issue:

Blocks inside a layout region are not sorted by weight property per default, even though the weight is used for rendering in the rendering process. But when you work with the blocks in a template directly you can't make sure they appear in the right order.

Solution:

Preprocess the regions and use the Drupal Core sortByWeightProperty mechanism to change the order of the blocks in the array before entering the template.
