🔧 Bug Fixes & Patches (6)

  • Fixed #9109, where the GitHub reporter wasn't correctly enabled when `biome ci` runs on GitHub Actions.
  • Fixed #9107: The HTML parser can now correctly parse Astro directives (client/set/class/is/server), which fixes the formatting for Astro directives.
  • Fixed #8882 and #9108: The Astro frontmatter lexer now correctly identifies the closing `---` fence when the frontmatter contains multi-line block comments with quote characters, strings that mix quote types (e.g. `"it's"`), or escaped quote characters (e.g. `"\"`).
  • Fixed #9141: The `noUnknownAttribute` rule no longer reports `closedby` as an unknown attribute on `<dialog>` elements.
  • Added missing Mocha globals to the `Test` domain: `context`, `run`, `setup`, `specify`, `suite`, `suiteSetup`, `suiteTeardown`, `teardown`, `xcontext`, `xdescribe`, `xit`, and `xspecify`. These are injected by Mocha's BDD and TDD interfaces and were previously flagged as undeclared variables in projects using Mocha.
  • Fixed #8840. Now the Biome CSS parser correctly parses `not + scroll-state` inside `@container` queries.
