#37328: Empty <p> tag inside <figure> markup

 {{{
 <figure>
 <img src="image.png" alt="">
 <figcaption>Caption</figcaption>
 </figure>
 }}}

 Using the above markup in the form at Posts > Add New results in an empty
 {{{<p>}}} tag being output. For example:

 {{{
 <figure>
 <img src="image.png" alt=""><p></p>
 <figcaption>Caption</figcaption>
 </figure>
 }}}

 Interesting, if I remove all whitespace from the markup I enter in the
 post form:

 {{{
 <figure><img src="image.png"
 alt=""><figcaption>Caption</figcaption></figure>
 }}}

 ... I get a {{{<br>}}} tag instead of the {{{<p></p>}}}:

 {{{
 <figure><img src="image.png" alt=""><br>
 <figcaption>Caption</figcaption>
 </figure>
 }}}

 I believe the empty {{{<p>}}} is a bug with {{{wpautop()}}}.
