Another conflict

Allright.. Here's another question :)

Consider the following example document-tree:
  * HTML (margin,border,padding:0; height:auto)
    * HEAD (ignored)
    * BODY (margin,border,padding:0; height:auto)
      * P (margin,border,padding:0; height:auto)
        * anonymous inlinebox
          * "The quick brown fox jumped over the barbwired fence"

P's height will be 22px (10.6.3)

html.height will be viewport.height (9.1.2)
-> body.height will be viewport.height (10.6.3)
-> p.height will be viewport.height (10.6.3) (conflict!)

What should my program do to resolve the conflict?
