Style Sheets and comment form

An issue came up with rendering of the comment entry form. It seems to be due to some bug or missing capabilities in older (4.72, 4.78) Netscape's CSS engine and some quirk in the style sheets of eg bek.antville.org: the entry fields are squashed vertically and are unusable. With "Enable Style Sheets" disabled, the form fields get rendered correctely.

Did other ants observe the same problem, maybe with other browsers or weblogs?

Any CSS experts around?
