There is a generated-content-image before this text.
Before this text there is generated content, too.
However, the URL points to this HTML-File, not to an image.
Since Opera doesn't support this, it should
ignore the resource.
The exact style is:
#test2:before{
content: "alternative text";
content: url(test10.html);
}
So, since url(test10.html) should be ignored, "alternative text"
should be displayed instead.
But what Opera does is to display [Image] :-(
