Summary RenderViewTransitionCapture unconditionally allocates a backing store
Matt Woodrow
Reported 2024-10-24 18:33:22 PDT
The RenderLayerBacking for RenderViewTransitionCapture always allocates a backing store, since isSimpleContainerCompositingLayer always returns false for RenderReplaced subclasses. When being used for a ::view-transition-new() pseudo element, this layer just exists to attach other composited layers to, and doesn't draw anything itself (unless it has box decorations etc).
