test case

Atm, I can only repro this after implementing the fix for Bug 125829. I'll update this report with a test case that repro by simply turning subpixel on. (not requiring other changes)

<html>
<head>
<style>
    .links {
        font-size: 99%;
        padding: 10px;
    }
</style>
</head>
<body><ul class="links"></ul>foo</body>
</html>

This and Bug 125829 are more like placeholders to discuss the rounding strategy (if needed at all)

Same situation as bug 125757.
