There is a comment on RenderBox.h [1]:

// Whether or not the element shrinks to its intrinsic width (rather
than filling the width
// of a containing block).  HTML4 buttons, <select>s, <input>s,
legends, and floating/compact elements do this.

I guess that explains why we don't check CSS width for RenderFieldset
(intrinsic sizes are never impacted by CSS). If you told us why you
think this is wrong, we may be able to give a better answer.

Thanks,
Julien
