Can't edit the content of a post with no title

[wonderboymusic]

1. Add new post screen: post-new.php

2. Don't enter a title, enter some arbitrary content: "This is a post."

3. Click "Publish"

4. Erase the content, then press Update

*Spoiler alert: The content is still there*

5. Add a title

6. Repeat steps 3 & 4

*Works*

This is important because some post formats don't need a title

Thinking this should go the other way: the default posts can be without a title, but shouldn't be without content, i.e. saving or publishing a post of type 'post' or 'page' without content should be rejected.

Publishing is not necessary, reproduced with saving as a draft it as well.

Fixes this issue using similar technique from #23887

Thoroughly disagree. I use no-content posts all the time (say, to act as a page stub for a plugin to act upon).

Same, but removed 'link'

.2.diff removes "link" — if you don't have a title or content, there's nothing to wrap the link around.

In 23986:

Allow the content of no-title audio, video, quote, and image posts to be blanked.

props wonderboymusic. fixes #23623.

Right, have used that too. Wondering if we need to be looking at the post format meta fields when determining whether a post is "empty". For example: saving a video post with empty wp_format_video meta and no title or content.
