622297 - Underlining displaced downward

Status: NEW

(Core :: Layout: Block and Inline, defect)

Description

[Zack Weinberg (:zwol)]

In Firefox 4.0b8 and current trunk, some of the underlined items on http://www.tonyandalbaspizza.com/Menu.html have the underline displaced downward from where Firefox 3.6 draws it, to the point where it overlaps text on the line below.  The problem is not visible when the page first loads -- the first instance that I see is for "TONY GOURMET" (between "TONY SPECIAL" and "MARGHERITA", whose underlines are being drawn in the correct location).

This page is, um, not well coded.  I will attempt to extract a reduced test case.

Attachment: minimized test case

Here's a minimized test case.  The problem seems to be with nesting <u> inside and outside font-size overrides, but note also that removing the &#10;s or switching to the HTML5 doctype changes the behavior.

Turns out this isn't actually a regression from 3.6.  However, it *is* a difference from current Safari.
