#62870: Autosave Stores Default Taxonomy (Category) but Not Custom Taxonomies
--------------------------+-----------------------------
 Reporter:  praful2111    |      Owner:  (none)
     Type:  defect (bug)  |     Status:  new
 Priority:  normal        |  Milestone:  Awaiting Review
Component:  Autosave      |    Version:
 Severity:  normal        |   Keywords:

--------------------------+-----------------------------
 In the WordPress block editor, the autosave feature correctly stores terms
 from the default taxonomy {{{category}}}, but it fails to store terms from
 custom taxonomies. As a result, custom taxonomy terms assigned to a post
 are lost when relying on autosave, unless the post is manually saved.


 == Steps to Reproduce:
 ----
 1. Create a custom taxonomy using {{{register_taxonomy()}}} in WordPress
 and make sure {{{show_in_rest = true}}}.
 2. Assign the custom taxonomy to a post type.
 3. Open the block editor for the post type.
 4. Assign terms to both the default taxonomy (category) and the custom
 taxonomy.
 5. Wait for the autosave to trigger.
 6. Reload the editor without manually saving the post.


 == Expected Behavior:
 ----
 Terms for both the default taxonomy (category) and the custom taxonomy
 should be stored and restored by autosave.


 == Actual Behavior:
 ----
 Terms for the default taxonomy (category) are stored and restored
 correctly.
 Terms for the custom taxonomy are not stored, resulting in data loss.
