Description:
Hello. I’ve noticed that the ability to add additional data for an image (such as custom attributes) when inserting it into an article through the editor does not work directly in the Joomla Media Manager when editing the same image.

When adding an image via the article editor, extra data fields (e.g., custom attributes) are available and can be saved with the inserted image. However, when opening the same image in the Media Manager, these fields are not available.

Expected behavior:
It should be possible to access and modify the same set of image-related data directly from the Media Manager, or at least the functionality should behave consistently between the editor insertion dialog and Media Manager image editing.

Could you please clarify whether this is a bug, missing feature, or intended behavior?
Thank you!
