<!-- Please describe your changes on the following line: --> Implement `getProperties` for `StylePropertyMapReadOnly`. --- <!-- 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` does not report any errors - [X] These changes fix #17579. - [X] These changes do not require tests because the existing css-paint-api tests catch this (rather annoyingly, they all fail for different reasons, sigh) <!-- Also, please make sure that "Allow edits from maintainers" checkbox is checked, so that we can help you if you get stuck somewhere along the way.--> <!-- Pull requests that do not address these steps are welcome, but they will require additional verification as part of the review process. --> Source-Repo: https://github.com/servo/servo Source-Revision: b07f06ce9263177f01cde692d3ea5830a7dfdeeb
