BlocksPanel dropped a new Image block with an explicit `src=""` prop, which overrides ImageBlock's `src = PLACEHOLDER_SRC` default parameter (defaults only apply when a prop is undefined, not when it's an empty string). Craft then persisted `src:''`, and the canvas rendered a broken-image icon instead of the placeholder. - ImageBlock render now falls back to PLACEHOLDER_SRC whenever src is falsy (belt-and-braces: also recovers any legacy saved src:'' state). - BlocksPanel no longer passes src="" when dropping a new Image block, so the craft default applies. - ImageStylePanel now restores the placeholder (instead of blanking to '') when the URL field is cleared.
