    Web: Check for sizeless headings when building line contents
    
    Normally we want to present visual line contents in layout mode.
    But we include unrendered, sizeless objects on the same line
    because they are presumably there for accessibility purposes and we
    don't want their inclusion to break up the rest of the line. There is
    at least one site including an unrendered, sizeless heading right
    before the content. We should treat that heading, and those like it,
    as the full line.
