Flash object elements are broken in FF

[Wiktor Walc]

Confirmed on FF 3.5.5 @ WinXP/SP3.

Steps to reproduce

• start with

  <p><object width="660" height="525">
  <param name="movie" value="http://www.youtube.com/v/HwNXvQ2OK_k&hl=pl_PL&fs=1&color1=0x234900&color2=0x4e9e00&border=1"></param>
  <param name="allowFullScreen" value="true"></param>
  <param name="allowscriptaccess" value="always"></param>
  <embed src="http://www.youtube.com/v/HwNXvQ2OK_k&hl=pl_PL&fs=1&color1=0x234900&color2=0x4e9e00&border=1"
   type="application/x-shockwave-flash" allowscriptaccess="always"
   allowfullscreen="true" width="660" height="525"></embed>
  </object></p>
  

• switch to source mode
• result:

  <p><object height="525" width="660">
  <param name="movie" value="http://www.youtube.com/v/HwNXvQ2OK_k&amp;hl=pl_PL&amp;fs=1&amp;color1=0x234900&amp;color2=0x4e9e00&amp;border=1" />
  </object>
  <param name="allowFullScreen" value="true" />
  <param name="allowscriptaccess" value="always" />
  <embed allowfullscreen="true" allowscriptaccess="always" height="525" src="http://www.youtube.com/v/HwNXvQ2OK_k&amp;hl=pl_PL&amp;fs=1&amp;color1=0x234900&amp;color2=0x4e9e00&amp;border=1" 
  type="application/x-shockwave-flash" width="660">
  </embed></p>
  

  (<embed> and some <param> elements are outside <object> element)

This does not happen when params are created this way:

<param name="allowFullScreen" value="true" />

it only happens when params are created like this:

<param name="allowFullScreen" value="true"></param>

(YouTube does like that).

Defer it, at least it works for valid HTML.

The fixing seems to be simple, so let's have it back in 3.1...
Including the latest patch from #4856 for easy reviewing.

Please do not mix fixes from other tickets.

Fixed with [4790].
