`BUGFIX: Resolve proptype errors in Workspace.Ui <https://github.com/neos/neos-development-collection/pull/5758>`_
------------------------------------------------------------------------------------------------------------------

TranslationParameterToken are not valid as FormElement content and throw Exceptions when the PropTypes package is installed.

`BUGFIX: Add missing content type header to create-image-variant endpoint <https://github.com/neos/neos-development-collection/pull/5762>`_
-------------------------------------------------------------------------------------------------------------------------------------------

### Upgrade instructions

Currently, the enpoint ``/neos/content/create-image-variant`` does not set a ``Content-Type`` header and therefore uses the default ``text/html`` content type. This can lead to issues, if any of the used middlewares require a correct content type to be set. One example could be that you have a middleware that will add an attribute to all ``<script>``-Tags if the returned content type is ``text/html``. When using the php `DOMDocument <https://www.php.net/manual/en/class.domdocument.php>``_ or sth. similar to parse and update the content, this will result in the response being wrapped by a ``<p>`-Tag and therefore returns an error.

### Review instructions

To test this behaviour:

- Add a new middleware.
- Add sth. like the following to this middleware:
  ```php
  use GuzzleHttp\\Psr7\\Utils;
  
  // ...
  
  public function process(ServerRequestInterface $request, RequestHandlerInterface $next): ResponseInterface
  {
      $response = $next->handle($request);
      
      if (str_contains($response->getHeaderLine('Content-Type'), 'text/html')) {
          $content = $response->getBody()->getContents();
          
          // This is one case, that could result in an issue with the current state.
          $dom = new \\DOMDocument();
          libxml_use_internal_errors(true);
          $dom->loadHTML($content, LIBXML_HTML_NOIMPLIED | LIBXML_HTML_NODEFDTD);
          libxml_use_internal_errors(false);
          
          $scripts = $dom->getElementsByTagName('script');
          foreach ($scripts as $script) {
              $script->setAttribute('x-custom-attribute', 'some-value');
          }

          $newContent = $dom->saveHtml();
          
          $response = $response->withBody(Utils::streamFor($newContent));
      }
      
      return $response;
  }
  ```

`BUGFIX: Variadic argument in SubtreeTags::with() <https://github.com/neos/neos-development-collection/pull/5749>`_
-------------------------------------------------------------------------------------------------------------------

This fixes https://github.com/neos/neos-development-collection/issues/5748 by unwrapping the existing subtreeTags and the subtreeTagsToAdd in a different manner.

Resolves ``PHP Fatal error: Cannot use positional argument after argument unpacking`` when using the FlowQuery ContextOperation with ``{invisibleContentShown: false}``

`BUGFIX: Ignore impending hard removal conflict table in migrations <https://github.com/neos/neos-development-collection/pull/5747>`_

`TASK: allow aop to extend `AssetUsageIndexingService::extractAssetIds` <https://github.com/neos/neos-development-collection/pull/5753>`_
-----------------------------------------------------------------------------------------------------------------------------------------

Because the method is private aop is not applicable which is unfortunate, as a simple extension here does no harm if done correctly and deterministic:

```php
#[Flow\\Aspect()]
class AssetUsageExtractionAspect
{
    #[Flow\\Around('method(Neos\\Neos\\AssetUsage\\Service\\AssetUsageIndexingService->extractAssetIds())')]
    public function extractAssetIdsFromValueObjects(JoinPointInterface $joinPoint): array
    {
        $nodePropertyValue = $joinPoint->getMethodArgument('value');
        if ($nodePropertyValue instanceof MyValueObject) {
            return [$nodePropertyValue->myAssetId];
        }
        return $joinPoint->getAdviceChain()->proceed($joinPoint);
    }
}
```

We discussed already a proper official extension point for this but AOP should be enough while we figure out what we need.

Demonstration of current plugins which would profit from working asset usage:

Asset ids from Value objects and collections:

Asset ids encoded into the body as data attribute for inline images

For this reason this PR targets Neos 9.0 deliberately and is intended to be released as patch. Our modern code style often destroys older features like Flows AOP. Unplanned extensibility is a feature we have and promote and we should not stand its way.
