Default category for custom posts when post_content is empty

[tmatsuur]

If you enter only the post_content and save, or enter the post_title and post_content and save, the default category is selected and it works as intended.

But when I type in only the post_title and save it, no categories appear to be selected.

Upon investigating the reason, if no post_content is entered, the post_status value will be "auto_draft" and as a result the default category will not be applied.

Is the above as expected?

But when I type in only the post_title and save it, no categories appear to be selected.

This wasn't accurate.

There was a problem when the [Publish] button was clicked without entering the title and moving the "focus" to other places even once.
