Without a path the screenshot was written into a private temp directory, and std::env::temp_dir panics on wasm32 (no file system), which stopped the whole web app: the page's call never got a reply and nothing after it ran. On wasm the PNG now comes back inline (pngBase64, width, height, bytes), as ui.render's does. Native builds are unchanged.
