Steps to reproduce:

		</clipPath>
		<clipPath id="clip2" clip-path="url(#clip1)">
			<rect x="020.0" y="065.5" width="70.0" height="25.0"/>
		</clipPath>
		<clipPath id="clip3" clip-path="url(#clip2)">
			<rect x="060.0" y="065.5" width="70.0" height="25.0"/>
		</clipPath>
		<g>
			<rect x="020.0" y="065.5" width="70.0" height="25.0" fill="red" opacity="0.5"/>
			<rect x="060.0" y="065.5" width="70.0" height="25.0" fill="green" opacity="0.5"/>
			<rect x="040.0" y="076.5" width="70.0" height="25.0" fill="blue" opacity="0.5"/>
		</g>
		<path stroke="Red" stroke-width="5.5" fill="with" d="M 098.0 099.0 041.0 050.0" clip-path="url(#clip3)"/>
</svg>


Actual results:

Red stroked path is not visible after the 3rd clip-path intersection. It becomes visible by changing clip-path attribute to "url(#clip2)" for red stroked path. Obviously, clip-path intersection works only up to level 2.


Expected results:

Expected result is stroked path visble after the 3rd intersection, which is true for Opera (12.16) and IE (10.0.9200.16750). I was surprised to see this example working on Safari (WebKit) for iPhone/iPod 1st gen (iOS 3.3.x)!

Actually, old Safari mobile is doing union here, not intersection. I assume intersection is working properly for a new WebKit based browsers.
