FWIW, I've checked that Batik Squiggle also matches the Opera

It seems that the behavior was apparently not undefined, it was an
implementation issue which got fixed. :-)

And yes, I'd also say this could be a nice addition to the test suite.
If not, I'd suggest contributing it to the SVG Torture Tests [1]
