[CSS Grid Layout] Tracks shrink sometimes with undefined remaining space

The third step of the grid track sizing algorithm (method
ComputeUsedBreadthOfGridTracks in the old specs version of the algorithm)
tries to grow all grid tracks until the remaining space is exhausted. Should
the remaining space is undefined we should fill the tracks up to their
limits. This is specified in pseudocode like this:

    For each Grid track t in GridTracks
        t.UsedBreadth = t.MaxBreadth

That's correct for most of the cases, but it becomes wrong whenever
t.UsedBreadth > t.MaxBreadth something that is not incorrect. What we
actually want to do is to grow the track to its maximum if and only if the
used breadth is smaller than the maximum.
