v1.43.0

## New APIs
- Method [browserContext.clearCookies()](https://playwright.dev/docs/api/class-browsercontext#browser-context-clear-cookies) now supports filters to remove only some cookies.
  
  ```js
  // Clear all cookies.
  await context.clearCookies();
  // New: clear cookies with a particular name.
  await context.clearCookies({ name: 'session-id' });
  // New: clear cookies for a particular domain.
  await context.clearCookies({ domain: 'my-origin.com' });
  ```
  
- New mode `retain-on-first-failure` for [testOptions.trace](https://playwright.dev/docs/api/class-testoptions#test-options-trace). In this mode, trace is recorded for the first run of each test, but not for retires. When test run fails, the trace file is retained, otherwise it is removed.
  
  ```js title=playwright.config.ts
  import { defineConfig } from '@playwright/test';
  
  export default defineConfig({
    use: {
      trace: 'retain-on-first-failure',
    },
  });
  ```
  
- New property [testInfo.tags](https://playwright.dev/docs/api/class-testinfo#test-info-tags) exposes test tags during test execution.
  
  ```js
  test('example', async ({ page }) => {
    console.log(test.info().tags);
  });
  ```
  
- New method [locator.contentFrame()](https://playwright.dev/docs/api/class-locator#locator-content-frame) converts a `Locator` object to a `FrameLocator`. This can be useful when you have a `Locator` object obtained somewhere, and later on would like to interact with the content inside the frame.
  
  ```js
  const locator = page.locator('iframe[name="embedded"]');
  // ...
  const frameLocator = locator.contentFrame();
  await frameLocator.getByRole('button').click();
  ```
  
- New method [frameLocator.owner()](https://playwright.dev/docs/api/class-framelocator#frame-locator-owner) converts a `FrameLocator` object to a `Locator`. This can be useful when you have a `FrameLocator` object obtained somewhere, and later on would like to interact with the `iframe` element.
  
  ```js
  const frameLocator = page.frameLocator('iframe[name="embedded"]');
  // ...
  const locator = frameLocator.owner();
  await expect(locator).toBeVisible();
  ```
