[css-writing-modes-3] value-digits4-003 tests

Masataka,

http://test.csswg.org/source/css-writing-modes-3/text-combine-upright/value-digits4-003.html

Several text-combine-upright (tate-chu-yoko) tests you did are excellent 
although
some are rather long and forces scrolling up and down when taking the 
test harness.



By default, p elements have this rule from user agent style sheet:

p {margin: 1em 0;}

"
Beware! <p> has margins by default!
"
https://wiki.csswg.org/test/format#body-content

So, if font-size is 100px, then rendered content height may increase by 
200px just to render those black rectangles (or squares) if the browser 
has not logicalized margin-top as margin-start (like Firefox; but Chrome 
40 has). And we want tests to be taken with the test harness which uses 
about 400px tall.
Even in Chrome 40, it's still rather long: rendered content height is 
551px tall.

"
Tests should be as short as possible. For reftests in particular 
scrollbars at 800×600px window size must be avoided unless scrolling 
behaviour is specifically being tested.

By definition, "the X/HTML div element is assigned display: block; and 
no other property declaration."

I suggest to change the code to use inner divs (instead of p) and to 
reduce the font-size to 5em (computes to 80px). 5em is also more 
scalable, less rigid than px unit.


line 11: <style>
div#test {
   writing-mode: vertical-rl;
   font: 5em/1 Ahem; /* computes to 80px/80px */
}

div > div {margin-right: 0.125em;} /* computes to 10px */

.tcy {
   text-combine-upright: digits 4;
}
</style>
</head>
<body>

<p>Test passes if there are 2 <strong>identical</strong> black 
rectangles.</p>

<div id="test">
   <div><span class="tcy">12345</span></div>
   <div>xxxxx</div>
</div>

In this case, your test would not require a mismatch reference to 
control support of writing-mode.
