It also makes sense to integrate this other change too:

    Remove an extra relayout for non-percent logical height grid items

    The only reason for a grid item to force a relayout after a grid
    area's logical height change is if it has a percentage height. In
    all other cases, this would cause an unneeded relayout. Note that
    changing the logical width still forces a relayout as the situation
    is not that simple.

    This improves auto-grid-lots-of-data.html from 94 runs/s to 226
    runs/s as we avoid a relayout in layoutGridItems for every grid
    items.
