…t` (#762) Playwright 1.63 removed `@playwright/experimental-ct-react`. Component tests now use the `mount(storyId, props)` fixture of `@playwright/test`, following the stack used in RADES: * Serve the Playwright Component Testing page in `tests/playwright/ct/` with `webpack-dev-server` (new devDependency), using the loader rules and module resolution of the library build. Playwright starts it through `webServer`. Enable `React.StrictMode`, `reuseContext` and `serviceWorkers: 'block'` as recommended by Playwright. * The project `mount` fixture returns the rendered component element, so snapshots keep their bounds, parks the mouse pointer outside the viewport and provides `getSpyValue()`. * Specs mount stories by ID with plain data props. Callbacks are asserted through `*SpyForTest` stories using `withSpy` / `useSpy`. Assertions that a callback was called are translated as `toContain(true)`, not as exact call counts. * Unlike RADES, react-ui passes JSX in props (icons, nodes as labels, sort icons). Such props are described with plain data by `element()` and turned back into elements by the page. Compositions of library components in `InputGroup` children are rendered by the story. * Portal tests add the portal after mounting, because `mount()` reloads the page, and re-render the story into it with `update()`. * Update the `playwright` image in Docker and CI to 1.63.0. Snapshots with a `textarea` are re-baselined: Chromium shipped with Playwright 1.63 renders the native resize handle differently. All other snapshots are unchanged.
