servo: Merge #14347 - Only allow border-image-outset to use non-negative numbers (from jcdyer:cdyer/len-parsing); r=Wafflespeanut Restricts border-image-outline to only allow positive values. Fixes #14295 --- <!-- 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 #14295. <!-- 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. --> Source-Repo: https://github.com/servo/servo Source-Revision: 210b1be1d093adf3a4fb4d4360c6e016676f34be
