5176 - M4 results of W3C CSS Test Suite

Status: VERIFIED DUPLICATE of bug 5469

(Core :: CSS Parsing and Computation, defect, P3)

Description

[Morten Wang]

I ran my w32 version of M4 (Build ID 1999041412) through the CSS Test Suite on
W3C's web site and found the browser to have trouble with the following tests:

4.3 replaced elements - the size of the images is incorrect in the table
section.

5.3.5 background attachment - browsers may treat 'fixed' as 'scroll' but
shouldn't it actually be able to do 'fixed'?
5.3.7 background - ditto

5.4.3 text-decoration - the image in the 9th paragraph isn't underlined as far
as I can see.

there's no border for the table cells in the following tests:
5.5.18 border-top
5.5.19 border-right
5.5.20 border-bottom
5.5.21 border-left
5.5.22 border

5.5.25c float - the small orange image supposed to be adjacent to the
right-floating paragraph is not adjacent.  instead it's aligned to the left
margin.

on the same page (5.5.25c) there is a paragraph inside a DIV element which is
floated inside another paragraph.  this DIV with a yellow background floats on
top of the two paragraphs/DIVs following it.  this behaviour does not happen in
the table section though, where the paragraphs underneat it get their top
aligned after the bottom of the previous element.

the previous problem follows through to the acid test, 5.5.26c where the
rendering is very different from the reference.  therefore my view is that
5.5.25c is not rendered correctly, and the error happens again on the acid test.
 in the previous version I tested (M3) it did get the acid test right.

in tests '5.6.5 list-style-position' and '5.6.6 list-style' the text isn't put
underneath the list item like it should, but instead follows a left margin
collected from the first text-item after the list item.

it also seems to me that there's a problem with word wrapping when style is
applied to an inline text element.  as seen in text 5.5.05b where the element
with a -10px margin is incorrectly wrapped (and unwrapped) when the browser
window is made wider or narrower.

While I greatly appreciate you taking the time to run through the test suite and
provide such detailed information. Please, in the future, file each issue under
a seperate bug. Nine issues under one bug report makes it extremely difficult to
hand the bug reports to the appropriate people and track status.

4.3: duplicate of bug 5272
5.3.5, 5.3.7: duplicate of bug 1045
5.4.3: duplicate of bug 1019, bug 1777
5.5.18-5.5.22: duplicate of bug 1055
5.5.25c: duplicate of bug 2025, and already fixed
5.5.25c: duplicate of bug 4572
acid test: ?? - never seen this, worksforme
5.6.5, 5.6.6 - duplicate of bug 1049

Therefore I think the only new bug here is the last one you report, on
5.5.05b.  That is a bug that should be filed under layout.  I will file it
separately later, and then resolve this one, after checking that I have checked
everything listed here.  (If someone else wants to do this, feel free, and cc:
me on the new bug.)

In the future, I maintain a list of CSS1 test suite results at:

You may want to check your bugs against the ones listed there before filing.

I reported the one new bug as bug 5469, so that that bug doesn't have all the
other stuff on it.  I am therefore resolving this bug as a duplicate of that.

*** This bug has been marked as a duplicate of 5469 ***

After David Baron's resolution of each issue, verified the last issue
regarding 5.5.05b. as a dup of #5469.
