Learning: In Rocket.Chat, there are two different `ModalBackdrop` components with different prop APIs. During review, confirm the import source: (1) `rocket.chat/fuselage` `ModalBackdrop` uses `ModalBackdropProps` based on `BoxProps` (so it supports `onClick` and other Box/DOM props) and does not have an `onDismiss` prop; (2) `rocket.chat/ui-client` `ModalBackdrop` uses a narrower props interface like `{ children?: ReactNode; onDismiss?: () => void }` and handles Escape keypress and outside mouse-up, and it does not forward arbitrary DOM props such as `onClick`. Flag mismatched props (e.g., `onDismiss` passed to the fuselage component or `onClick` passed to the ui-client component) and ensure the usage matches the correct component being imported.

Timestamp: 2026-05-06T12:21:44.083Z
Learning: Field wrappers in rocket.chat/fuselage-forms (Field, FieldLabel, FieldRow, FieldError, FieldHint) auto-create htmlFor/id associations, aria-describedby, and role="alert" for errors. Do not manually set htmlFor, id, aria-describedby, or role attributes when using these wrappers. This automatic wiring does not apply to plain rocket.chat/fuselage components, which require explicit ID wiring per the accessibility docs. In code reviews, prefer using fuselage-forms wrappers for form fields and verify there is no unnecessary manual ID/aria wiring in files that use these wrappers. If a component uses plain fuselage components, ensure proper id wiring as per docs.

Walkthrough

The PR removes explicit ReactElement return type annotations from six React components across the uikit-playground app. Import statements are updated to use ReactNode as a type-only import where children props are typed. No runtime logic or rendered output changes.

Changes

React component type refactoring

Layer / File(s)	Summary
BurgerIcon component family type updates apps/uikit-playground/src/Components/NavBar/BurgerIcon/BurgerIcon.tsx, apps/uikit-playground/src/Components/NavBar/BurgerIcon/Line.tsx, apps/uikit-playground/src/Components/NavBar/BurgerIcon/Wrapper.tsx	The BurgerIcon, Line, and Wrapper components remove explicit ReactElement return type annotations and use ReactNode as a type-only import for children props.
UI wrapper and container components apps/uikit-playground/src/Components/Preview/Display/UiKitElementWrapper/UiKitElementWrapper.tsx, apps/uikit-playground/src/Components/navMenu/Menu/Wrapper.tsx	ElementWrapper and Wrapper components in different contexts remove explicit ReactElement return types, with ReactNode imported as a type-only import.
Context provider children type update apps/uikit-playground/src/Context/createCtx.tsx	The createCtx factory function updates the returned Provider component's children prop type from ReactElement to ReactNode, with the React import updated to ReactNode type-only.
