Assertion:
In Netscape 6 Beta 1, a black bordered box was automatically placed around the LEGEND content (equivalent of using <legend STYLE="border: 2px solid black">). In later versions, no border box is applied.

If the behavior is as described, both cases should look alike.

Fieldset with normal LEGEND element:
filler text
this is a legend
filler text


Fieldset with LEGEND element having style="border: 2px solid black":
filler text
this is a legend
filler text
