Reading from <param> does not work in IE

[Sa'ar Zac Elias]

Using the following:

<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000"><param name="wmode" value="opaque" /><param name="quality" value="medium" /><param name="movie" value="a.com" /><embed src="a.com" type="application/x-shockwave-flash"></embed></object>

Right click on the placeholder, switch to the 2nd tab.
Note that all fields have their default values, although the params should override them.
Tested with IE8, works well with IE9's IE8 mode.
