Editor changes to images within richtext field are not applied on frontend

[indebit]

I found that at least 3 changes that are made within the Ibexa backoffice on a embed image, are not applied on the front-end.

Current setup:

• Ibexa DXP 4.6.10
• Netgen SiteAPI ^6.1.6

Steps to reproduce:

• Add an image within a richtext field for a certain Content
• Set a link to that image (maybe also a title for the link and/or set the target)
• Set a custom size from the default predefined sizes for that image
• Align the image to any side or center
• Publish the changes

Expected behavior:

• Changes made within the CMS are reflected on the frontend

Current behavior:

• The image is rendered without any changes made on the backoffice: No anchor () tag at all, no alignment and no custom size set.

I was in contact with Ibexa support as well regarding this issue, and they couldn't replicate the issue on their instances (without Netgen Ibexaa SiteAPI installed), so they pointed out to the usage of Ibexa Site API, because the value stored within the database is correct:

They suggested to disable Netgen Ibexa SiteAPI and to try it out, which I did, and indeed, the link tag showed up on the frontend (see screenshot attached).

I've also did some debugging and found that the vendor template (vendor\ibexa\core\src\bundle\Core\Resources\views\content_fields.html.twig) doesn't have any value for the parameters (line 443), as it's only an empty array. (see screenshot attached)

This is the preview from the backoffice, which confirms that Ibexa's default behavior renders the richtext field (including links attached) correctly
