Yes. This page is still pretty bad.

It seems like this is just using color matrix. I wonder why it's not being accelerated.

The filter appears to be part of the definition of a mask, so won't be using WebRender directly.

It looks like we support masking in WR (though not yet when the masked content is within an SVG blob), but even then the actual mask image always creates a blob, so that would still record the filter.

I think we'd need support for masking with a separate display list/pipeline before we can properly accelerate this.
