The markup you provided is not up to spec for HTML4 or XHTML.  I assume however that you intended it to be HTML4 because it has an unclosed tag and no body/head/title/html tags or DOCTYPE declared.
In the HTML4 spec available at http://www.w3.org/TR/html4/ (the version I used was  the current latest revision: http://www.w3.org/TR/1999/REC-html401-19991224) there are several components which taken together render your markup invalid HTML4 so Gecko closed the <p> tag when it could no longer be open.  To see the exact markup for the DOM that Gecko used, visit the page with markup from comment 0, hit ctrl-A or cmd-A on Mac, then right click the page background or text and select "View Selection Source".

"Generally, inline elements may contain only data and other inline elements."
<http://www.w3.org/TR/html4/struct/global.html#block-inline>

The 'p' element section lists <p> as an inline element in the first line of the DTD snippet and states "The P element represents a paragraph. It cannot contain block-level elements (including P itself)."
<http://www.w3.org/TR/html4/struct/text.html#edef-P>

The 'form' element section lists <form> as a block level element in the first line of the DTD snippet.
<http://www.w3.org/TR/html4/interact/forms.html#edef-FORM>

The behavior exhibited here is intentional and up to spec.  You should probably be using a DIV element instead here.
