- First commit to issue fork.
The THRON module is currently not compatible with Drupal 11. When attempting to use it in a modern Drupal installation, several issues arise:
- Composer constraints do not allow installation with `drupal/core:^11`.
- Adding a THRON Media field to a content type using "HTML tag" or "Thron Player" formatters causes rendering errors.
- Media thumbnails do not display correctly under `/admin/content/media`.
- Image cropping does not function as expected when uploading a media item via the entity browser.
- The CKEditor button for THRON appears with a generic "E" icon instead of the correct THRON logo.
These issues significantly limit the usability of the module in current Drupal setups and hinder integration with other media workflows.
1. Install the `drupal/thron` module on a Drupal 11 site.
2. Try adding a THRON Media field to a content type.
3. Attempt to render the media field using the "HTML tag" or "Thron Player" formatters.
4. Use the CKEditor THRON button — observe the missing icon.
5. Go to `/admin/content/media` — thumbnails for THRON media are not shown.
6. Upload a THRON media item via the entity browser and attempt to crop an image.
A patch has been created that:
- Updates module info and constraints to support Drupal 11.
- Fixes rendering errors in the HTML Tag and Thron Player formatters when used with entity reference fields pointing to THRON media.
- Restores the proper display of thumbnails for THRON media entities in `/admin/content/media`.
- Resolves image crop issues when uploading THRON media via the entity browser.
- Corrects the CKEditor button icon to show the appropriate THRON logo.
All changes are backward-compatible with Drupal 10.x, and the patch has been tested in real Drupal 11 environments.
- Review the patch for coding standards.
- Test the patch on clean Drupal 10 and 11 installations.
- Confirm compatibility with CKEditor 5 if relevant.
- Obtain feedback from maintainers and users.
- Correct THRON logo now displays on the CKEditor button.
- Thumbnails for THRON media are visible on the media overview page.
- No regressions or new elements introduced to existing UIs.

Due to strict version constraints in the module and its dependencies, it is currently necessary to use `composer-drupal-lenient` to allow installation on Drupal 11. Until the module’s `info.yml` and `composer.json` are updated upstream, use the following commands:
composer require mglaman/composer-drupal-lenient
composer config --merge --json extra.drupal-lenient.allowed-list '["drupal/thron"]'
composer config --merge --json extra.drupal-lenient.allowed-list '["drupal/media_entity_browser"]'
composer config --merge --json extra.drupal-lenient.allowed-list '["drupal/ckeditor"]'
composer config --merge --json extra.drupal-lenient.allowed-list '["drupal/media_entity_browser_media_library"]'
