[multicol] set width of multicol block not dividable by number of columns without creating fraction

Hello,

Example given:

http://test.csswg.org/suites/css3-multicol/nightly-unstable/html4/multicol-fill-000.htm

line 10 <style type="text/css">
div, table {
  font: 10px/10px Ahem;
  margin: 1em 0;
  color: lime;
  background: yellow;
  width: 400px;
}

div.multicol {
  columns: 3;
  column-gap: 0px;
  column-rule: none;
  column-fill: balance;
}


What is supposed to happen when the width is not dividable by the number
of columns without a fractional remainder?

Each <p> should be 133.33333px wide?
Or the first one should be 134px?
Or the last one?
It's entirely UA-dependent.

Opera 11.64 DragonFly reports 133px for each <p>'s computed style width;
so, it seems it rounds down the fraction.

What I'm trying to say is that all these tests should avoid fractional
pixels situations.
