Created attachment 219456 [details] 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)
