Example - passes if you see a circle

An element is filled with a pattern #p1. The element gets masked as well. If this mask makes use of #p1 as well, then it fails.

This is probably a problem with the cycle detection code for SVG resources. For some reason the code detects a cycle even though this is absolutely fine. Creating a second pattern with a different id makes the example work.

The example passes if you see a circle.
