missing support for maskUnits and maskContentUnits, also, as per comments on the original bug: moved rect outside defs to fix a possible bug in the current implementation referring to change in the testcase to fix an issue needs further testing and a fix
This is a fundemental issue in our <mask> support. But <mask> itself is not common enough to warrent this being a P2.
wow, I'm kinda surprised this isn't fixed yet. Wildfox just implemented patternContentUnits, this can't be any different. Mostly we just need a test cast or two.
