    "title": "Playwright 1.58 removed _react= / _vue= selectors, :light suffix and launch({ devtools }) — use getByRole/getByTestId",
    "error": "",
    "body": "## Symptom\nAfter upgrading to Playwright 1.58+, selectors like `page.locator('_react=SubmitButton[enabled=true]')`, `_vue=...` or `css:light=...` fail because the engine no longer exists. `chromium.launch({ devtools: true })` no longer opens DevTools.\n\n## Cause\nPlaywright 1.58 (2026-01-23) removed the experimental `_react` and `_vue` selector engines, the `:light` selector engine suffix, and the `devtools` option of `browserType.launch()`. It also dropped WebKit on macOS 13. Later releases removed more long-deprecated APIs. 1.63 (2026-09-04) removed the `videosPath` / `videoSize` context options (use `recordVideo`), the `logger` option on `connect` / `connectOverCDP`, and `Locator.ariaRef()`.\n\n## Fix\n```ts\n// before\nawait page.locator('_react=SubmitButton[enabled=true]').click()\n// after: user-facing locators, matched against the rendered DOM\nawait page.getByRole('button', { name: 'Submit' }).click()\nawait page.getByTestId('submit-button').click() // add data-testid in the component\n```\n```ts\n// before\nconst browser = await chromium.launch({ devtools: true })\n// after\nconst browser = await chromium.launch({ args: ['--auto-open-devtools-for-tabs'] })\n```\n```ts\n// before (removed in 1.63)\nconst context = await browser.newContext({ videosPath: 'videos/' })\n// after\nconst context = await browser.newContext({ recordVideo: { dir: 'videos/' } })\n```\nReplace `css:light=` with standard CSS selectors.\n\n## Verify\n`grep -rnE \"_react=|_vue=|:light=|devtools: true|videosPath\" tests` returns nothing, and the suite passes.\n\n## Sources\n- https://playwright.dev/docs/release-notes",
