Hi Simon,

thanks a lot for the investigation. Some details why the code changed recently:
We had a long-standing hack in SVGStopElement, to do manual style resolution,
because of svg/W3C-SVG-1.1/pservers-grad-19-b.svg, which used code like:

<g display="none">
<linearGradient>
<stop>
...

RenderSVGGradientStop was never created because of the display="none" in the
parent <g>.
To remove manual style resolution hacks (calling styleForRenderer() manually) I
made SVGGElement always create renderers, even for display="none"
(RenderSVGHiddenContainer, instead of the regular
RenderSVGTransformableContainer).

For <defs> a RenderSVGHiddenContainer is always created, so renderers are
_supposed_ to be created.
I will investigate today what is happening, stay tuned.
