Thank you for contributing to Servo! Please replace each `[ ]` by `[X]` when the step is complete, and replace `__` with appropriate data: - [X ] `./mach build -d` does not report any errors - [X ] `./mach test-tidy --faster` does not report any errors - [X ] These changes fix #11320 (github issue number if applicable). Either: - [X] There are tests for these changes OR - [ ] These changes do not require tests because _____ Pull requests that do not address these steps are welcome, but they will require additional verification as part of the review process.
