Invalid filter effects should not render.

An example of this is svg/filters/feConvolveMatrix-invalid-targetX.svg.

tesy-invalid-filters

HTML elements with invalid CSS filters or referenced SVG filters are displayed without the filter. But SVG elements with invalid SVG filters are not displayed at all. See the attached test case. Where did we get this weird behavior? Is this speced somewhere?

I personally prefer to see the element displayed without the filter more than displaying nothing.
