 With the following input
 {{{
 $input      = "<div>\n<div></div>\n" .         "<span></span></div>\n";
 }}}

 wpautop produces the unexpected output
 {{{
 $unexpected = "<div>\n<div></div>\n" . "<p>" . "<span></span></div>\n";
 }}}

 This is very similar to #39377.
 Note: I added the newlines to the input to make the difference more
 obvious.

 - div before span gives p
 - span before div gives /p

 == Workaround ==

 For my affected plugin I've written a PHPUnit test case that will fail
 when wpautop's behaviour no longer produces the unexpected results.
 And I'm changing my code to avoid mixing spans and divs.
