It is to align Webkit behavior with Gecko / Firefox and Blink / Chrome.

When removing the border attribute the table should look the
same as if the border attribute was never given. So when
we notice the border attribute is removed, make sure
m_borderAttr is set to false so the border will be
removed visually.
