Thumbnail is not language-aware

Created on 17 March 2017, over 7 years ago

Updated 27 October 2023, about 1 year ago

Problem/Motivation

When (re)generating the thumbnail of a media entity (using custom code #2798251: Thumbnail not updated → or with #2749695: Thumbnail not updated → ), the thumbnail generated in automaticallySetThumbnail is stored for all languages, even if the data used by the plugin to generate the thumbnail is translatable.

Steps to reproduce:

Use a patch to update media thumbnails
Use media_entity_image with a translatable image field
Create an image media entity with image A for a language (say, en)
(thumbnail will be generated for image A)
Translate this entity to another language (say, de) and use image B instead
(thumbnail will be generated for image B)

Expected result:
The English media translation uses thumbnail based on image A while the German media translation uses a thumbnail based on image B.

Actual result:
Both the English and German translations use the thumbnail based on image B (the most recent).

Proposed resolution

Would it be enough to mark the thumbnail as translatable?

Remaining tasks

Add tests, decide on an approach and implement it.

If you use patch #134 from https://www.drupal.org/project/drupal/issues/2983456 ✨ Expose triggering update of media metadata + thumbnail to end users Needs work and enable file translation for media image at "/admin/config/regional/content-language" and also set "translatable elements" in the bottom of "/admin/structure/media/manage/image/fields/media.image.field_media_image" then thumbnail translation works. Patch that is attached here is already included in patch #134 I mentioned above.
