We fail this interop-2023-relevant test:

Looking at the [test-failure-comparison](https://wpt.fyi/analyzer?screenshot=sha1%3A6d97c92689bcba5d15fbe86370aa30a98e8f2bbe&screenshot=sha1%3A99115423e64b712e526132ad863627249cd2ac24),  it seems mostly like just annotatable fuzziness, though it's quite a lot:
```
maxDifference: 255
totalPixels: 878 
```

The `maxDifference:255` is from a single pixel near the top left corner of the shape that's red in the testcase vs. lime in the reference case (255 in the red channel vs. 255 in the green channel).  (This is super weird since that red pixel seems to be surrounded by lime pixels... I also don't see that red pixel when I view the testcase locally.)

The large "totalPixels" is from antialiasing differences along the edge of the shape. It looks like the shape in the testcase is ~1px larger than the reference case on all sides, or something like that.
