I've not actually tried to run any of the CSS 2.1 tests on Windows 
myself, so no. :)

Our regression tracking system takes screenshots at 1600x1200 (by 
default), which is wide enough as to make D appear split between lines.

My local browser ends up (after all the chrome around it) with a 
viewport of 902x643, which is narrow enough to make B appear split 
between lines.

As far as I can tell, there are only a few ranges of width where it will 
actually end up with the big/small coloured boxes on the same line as 
each other.

For 
<http://www.gtalbot.org/BrowserBugsSection/css21testsuite/c414-flt-ln-002-draft.htm>, 
I wonder if it is worthwhile setting an explicit width on the div and 
using Ahem so that it is predicable exactly where the lines will break.

I dislike, "You can resize the window to change respective position of 
boxes and you can increase/decrease the font size to verify", as it is 
impossible to do within any regression tracking system pretty much. 
Given a screenshot, you can't just increase/decrease font size to 
verify. It's also pretty much impossible to change such a test into a 
reftest. In general, having a TC that's pretty much impossible to 
automate seems bad.
