We're using the core media library and core embed button with ckeditor. Unfortunately after an image is embedded from the media library the "edit" button only allows editing the alt tag, not the custom fields that are part of our image media items (such as caption, attribution).
If we edit the image from the media library we see all of the fields that we want to edit.
Also I notice the contrib media embed button does allow this functionality, but the core one does not.
To explain another way:
When I add an image to a content area using ckeditor the image embeds fine, but there's no option to edit anything about the image except the alt tag.
1) I insert an image into a wysiwyg field using the core embed button:
The image shows up in the editor and has an edit button next to it:

Clicking the edit button does not go to the edit screen to edit all image fields but instead goes to an abbreviated edit that only includes the alt tag.

It does not even show the name of the image so that I can search for it in the media library :/
If instead I find the image in the media library and edit it from there (using the small pencil icon) ...

I can edit all of the important image fields like caption, copyright year, media source, and more.

Also, I notice the contrib module "Media Entity Embed" doesn't have this problem, does allow accessing and editing these extra fields. (clicking on the selected entity link goes to the full image media edit screen as shown in Screenshot 3 above) .

Is there a way to edit image media entities from the wysiwyg editor? Thanks to anyone who can help!
