User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X 10.5; en-GB; rv:1.9.0.6) Gecko/2009011912 Firefox/3.0.6

The url should render a red blob on top of a red blob. (This is confirmed to work in WebKit, Opera and Batik). However, Firefox only renders the black blob, which references a mask defined in userSpaceOnUse units, and not the red blob, which references a mask defined in objectBoundingBox units.

Reproducible: Always

Steps to Reproduce:
1. Define a mask using
maskContentUnits="objectBoundingBox" maskUnits="objectBoundingBox"
2. Reference said mask.
mask="url(#…)
Actual Results:  
Rendered black blob.

Expected Results:  
Rendered a red blob on top of the black blob.

Attachment: Two blobs produced by masks

The black blob is produced via a mask defined using userSpaceonUse units, the red blob is produced via a mask defined using objectBoundingBox units. The correct rendering is a red blob on top of a black blob.

Apologies:
It should render a red blob on top a _black_ blob.

Seeing the same behavior with Tiger-PPC running a 2.0b3pre version of Camino (1.9.0.8pre 2009022319), so this issue isn't Leopard-only.

Fixed by bug 489151. The tests checked in there also cover this.
