[bug] getStoryContext() does not include all the story tags as defined in the index.json file

[rgylesbedford]

Describe the bug

I am attempting to use the tags to opt-out of specific tests within the test runner. The tags array on the context object returned from getStoryContext() does not match the tags as defined in the index.json file.

To Reproduce

1. Storybook is built using: storybook build --test
2. Test Runner is run with: test-storybook --junit --failOnConsole --ci --url http://127.0.0.1:6006
3. Using the following simplified ./storybook/test-runner.ts file; the tags array on the storyContext object is always ["story"].

   
   import type { TestRunnerConfig } from "@storybook/test-runner";
   import { getStoryContext, waitForPageReady } from "@storybook/test-runner";
   import { injectAxe, checkA11y } from "axe-playwright";

// See https://storybook.js.org/docs/writing-tests/test-runner#test-hook-api const config: TestRunnerConfig = { tags: { skip: ["skip-test"], }, async preVisit(page) { await injectAxe(page); }, async postVisit(page, context) { // See https://storybook.js.org/docs/writing-tests/test-runner#helpers const storyContext = await getStoryContext(page, context);

const skipA11y = storyContext.tags.includes("skip-a11y");
const skipVisual = storyContext.tags.includes("skip-visual");

// See https://storybook.js.org/docs/writing-tests/storyshots-migration-guide#run-image-snapshot-tests-with-the-test-runner
if(!skipVisual) {
  // removed for simplicity
}

// See https://storybook.js.org/docs/writing-tests/accessibility-testing#disable-a11y-tests-with-the-test-runner
if(!skipA11y) {
  await checkA11y(page, '#storybook-root', {
    detailedReport: true,
    detailedReportOptions: {
      html: true,
    },
  });
}

} };

export default config;

**Expected behavior**

The tags array on storyContext object matches the tags listed in the index.json file for the given story.

Tag handling changed dramatically in 8.1.0, so please give it another try int he latest version and let me know what you find.

Also it's possible some changes are needed in the test runner as well @yannbf https://github.com/storybookjs/test-runner/issues/453

Thanks. I got to testing the latest storybook this week and can confirm this is now working for me.
