Comment:

 In `wpautop` a block element immediately followed by an inline(-block)
 element causes this issue. For me it was `<div><img …>…</div>` getting
 turned into `<div><img …></p>…</div>`.

 The issue is that markup like this:

 {{{
 <div>
     <img src="https://source.unsplash.com/random/800x600" alt=""
 width="800" height="600" />
     <p>Here is some paragraph</p>
 </div>
 }}}

 gets split into

 {{{
 <div><img src="https://source.unsplash.com/random/800x600" alt=""
 width="800" height="600" />
 }}}

 {{{
 <p>Here is some paragraph</p>
 }}}

 {{{
 <div>
 }}}

 concatenated to


 {{{
 <p><div><img src="https://source.unsplash.com/random/800x600" alt=""
 width="800" height="600" /></p>
 <p><p>Here is some paragraph</p></p>
 <p></div></p>
 }}}


 The opening `<p>` then gets removed for the first fragment above in
 https://core.trac.wordpress.org/browser/trunk/src/wp-
 includes/formatting.php#L578 but the closing one stays.

 I've changed the severity to major, since this leads to invalid HTML
 markup in the output.
