widths cache except for whitespace == PRE.  The problem was that additional
        spaces in the RenderText's string were being inappropiately measured.
        An alternate, more complex and risky, fix would account for the whitespace
        properties during scanning of the RenderText width buffer.  Considering
        the scenario for which this optimization was added (3133261), this
        simpler fix is adequate.
