For native handlers, Opera can figure out the intrinsic dimensions and
use those if none are specified on the object, which is good.

For plugins in Opera, it's a different story. If you don't specify the
width and height on the object, the object will be 150 x 150. The only
way that it won't be is if the loaded plugin detects the dimensions of
the media it's loading itself and resizes itself, but I'm not sure
what plugins do that.

For example:
<object type="application/x-mplayer2">wmp</object>
<object type="application/x-java-applet">java</object>
<object type="video/quicktime">quicktime</object>
<object type="application/x-shockwave-flash">flash</object>
<object type="audio/x-pn-realaudio-plugin">realplayer</object>
<object type="video/divx">divx</object>
<object type="application/x-vlc-plugin">videolan</object>
<object type="application/x-xstandard">xstandard</object>
<object type="application/x-tcl">tcl</object>

<script>
window.onload = function() {
    var obj = document.getElementsByTagName("object");
    for (var i = 0; i < obj.length; ++i) {
        alert(getComputedStyle(obj[i], null).getPropertyValue("width"));
        alert(getComputedStyle(obj[i], null).getPropertyValue("height"));
    }
};
</script>

In Opera, (assuming you have all those plugins), you'll get 150px for
every one. Now, even if you give the plugin a 400 x 400 video to load
for example, it'll still show as 150 x 150 unless the plugin resizes
itself on its own.

If so, FF would need something like (made up):

object:loaded { width: 150px; height: 150px;} in its default style sheet.

(I could be mistaken, but that's how it appears to me.)
