It should just say "hey, this Canvas has a dirty list" and the frontend can request that list when it needs it (if the sidebar is visible). This pattern allows the backend to avoid constantly pushing nodes to the frontend that the frontend may never need.

Comment on attachment 314508 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=314508&action=review r=me The tests are failing, so you may have to mark them as flakey. We should really investigate that. > Source/JavaScriptCore/inspector/protocol/Canvas.json:79 > + { "name": "canvasId", "$ref": "CanvasId", "description": "Canvas identifier." } Nit: These descriptions are unnecessary. I think we can probably eliminate them for most $ref's. If someone needed this description they could get it by looking at the description of the Type itself. > LayoutTests/inspector/canvas/css-canvas-clients-expected.txt:13 > +PASS: Client node has valid ID. Why not just log the selector? Thats more useful.
