 Priority:  normal        |   Milestone:  Unassigned
Component:  Template      |     Version:  2.9       
 Severity:  minor         |    Keywords:  wpautop

 To reproduce, in a post enter:

 {{{
 <p>Welcome to WordPress. This is your first post. Edit or delete it, then
 start blogging!</P>
 }}}

 View the post (source) and you get:

 {{{
 <p>Welcome to WordPress. This is your first post. Edit or delete it, then
 start blogging!</P></p>
 }}}

 Because I (incorrectly) entered an uppercase closing </P> tag, wpautop()
 thinks there is no closing tag so adds a </p>, which then often renders as
 a double <p> tag. Close if this is not a bug, though I thought it may be
 good to do some sanitizing or something on uppercase tags.
