WP text formatting functions handle block-level INS tag incorrectly

[misieg772]

From W3C documentation:

"INS and DEL are used to markup sections of the document that have been inserted or deleted with respect to a different version of a document (e.g., in draft legislation where lawmakers need to view the changes).

These two elements are unusual for HTML in that they may serve as either BLOCK-LEVEL or INLINE elements (but not both). They may contain one or more words within a paragraph or contain one or more block-level elements such as paragraphs, lists and tables."

When I want to use INS tag as BLOCK-LEVEL element (to wrap to paragraphs for example) wrong HTML is produced:

<p><ins datetime="2008-11-14T14:45:27+00:00">First paragraph.</p>
<p>Second paragraph.</ins></p>

Correct HTML should look like this:

<ins datetime="2008-11-14T14:45:27+00:00"><p>First paragraph.</p>
<p>Second paragraph.</p></ins>

I think the same sitiuation occurs for DEL tag.

I use insert the same way... I'll look into this for 2.8

Closing as maybelater. Complete lack of interest on the bug on the ticket over the last 6 years. Feel free to reopen when more interest re-emerges (particularly if there's a patch).

No interest, but it's still a valid bug.

Given that these tags can be both block and inline level, it's not possible for wpautop() to distinguish which one was intended, so I'm going to close this ticket as something we can't fix.
