[css-paint-api] Should PaintRenderingContext2D have a filter attribute?

[foolip]

Per https://drafts.css-houdini.org/css-paint-api/#2d-rendering-context there shouldn't be a filter attributes on PaintRenderingContext2D, because there's no PaintRenderingContext2D includes CanvasFilters statements or similar that would make it so.

But Chromium does have a filters attributes here: https://source.chromium.org/chromium/chromium/src/+/master:third_party/blink/renderer/modules/csspaint/paint_rendering_context_2d.idl;l=39;drc=0c2640a413f8a95cefd92f01be76cc531eea1910

@mysterydate is there a spec PR for adding this?

The reason I noticed this is because MDN's browser-compat-data has a "filter" entry for this: https://github.com/mdn/browser-compat-data/blob/f3b0ec5cc89231ee0b528bdfbfeef92f5019e4cd/api/PaintRenderingContext2D.json#L530

But there's no spec IDL for it.

There's no spec PR for adding this from the canvas team. @xidachen, do you know if paint canvas is meant to support this?
