Summary [SVG] Clip paths referencing clip-paths do not work

Created attachment 156420 [details] Test case The SVG spec says: The ‘clipPath’ element or any of its children can specify property ‘clip-path’. If a valid ‘clip-path’ reference is placed on a ‘clipPath’ element, the resulting clipping path is the intersection of the contents of the ‘clipPath’ element with the referenced clipping path. If a valid ‘clip-path’ reference is placed on one of the children of a ‘clipPath’ element, then the given child element is clipped by the referenced clipping path before OR'ing the silhouette of the child element with the silhouettes of the other child elements. This is a mild contradiction, in that the clip-path property is not defined to apply to clipPath elements. However, Firefox does the expected thing.

The attached example works for me. And I am pretty sure that it worked since I spend a lot of my time to implement it :P I am aslo not sure what you meant with "that the clip-path property is not defined to apply to clipPath elements"? It is defined.

This is working for me on Linux/chromium at tip of trunk and 21.0.1180.57 beta.

It is defined. If you look at the property index, the thing that lists all the properties and what elements they apply to, it says that "clip-path" can be applied to container and graphics elements. However, the doc for "clip-path" itself says that it can apply to "container elements, graphics elements and clipPath". So the spec is inconsistent with the error certainly in the property index.

I cannot reproduce this. Very very odd. I've closed the bug.
