Status: RESOLVED DUPLICATE of bug 942341

This is similar to bug 942341, but I'm not sure this is really dup of it.

If <fieldset> element with <legend> element establishes containing box for absolute positioning, its top edge is bottom of <legend> on Gecko. However, on Chrome and IE, the top edge is same as the top edge of <legend>.

See the testcase:

And attached screenshot.

Although, I like the Gecko's behavior better. However, this difference makes web developers complain about us.

# <fieldset> with <legend> laid out like replaced element. So, I guess that there is no standard spec about this...

Sure looks like a dup to me.
