245938 - [standards mode]Space is inserted above headings in table cells

Status: RESOLVED INVALID

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

Description

[James Oldfield]

User-Agent:       Opera/7.50 (Windows NT 5.1; U)  [en]
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8a2) Gecko/20040531

When any heading is the first line of a table cell there should be no space inserted above that heading (note: this is UNLIKE <div>s, where this is correct behaviour).  Mozilla however does insert spacing above the heading; both the headings in the example URLs show this problem.

Reproducible: Always

We have no space in quirks mode, but do in standards mode.

I will also add that the W3C suggest that by default H1 gets a margin of .67em 0.

...which is exactly what we do.  (It's a 'margin' shorthand property with two
values, so .67em is the top and bottom margin and 0 is the left and right margin.)

Sorry David, that was not ment for you.  Shouldn't this bug be closed?
Also, the rest of the suggested defaults are located at

The current layout is correct for "Standards compliance mode".

-> INVALID
