3//! Register a webview panel through the `WebviewProvider` trait so the
4//! panel is tracked in `ApplicationState::WebviewState`. Without trait
5//! registration `DisposeWebviewPanel` later fails with "unknown handle"
6//! and webviews leak DOM. Falls back to a millisecond pseudo-handle and
7//! a direct Sky emit on trait failure.
