41d4de49d3c684c9f01bdb67262c08d46852f8f5 [Site Isolation] Web Inspector: Add Canvas support for frame targets
not a security fix
confidence 0.12
signal score 6.06
Source/JavaScriptCore/inspector
Classified as not security-relevant.
Triage note: Adds FrameCanvasAgent and moves didChangeCSSCanvasClientNodes/dispatch helpers from PageCanvasAgent into the shared InspectorCanvasAgent, with page agent staying out under site isolation; inspector feature work. The added if(!inspectorCanvas) returns after ASSERT are minor inspector-only guards.
