servo: Merge #17960 - Fix warning in scroll root id assignment to TableColGroupFlow (from mrobinson:fix-warning-for-table-colgroup); r=emilio
The traversal currently expects every flow to have a scroll root id assigned, even if it doesn't produce any display items. This change fixes the error that arises from this situation. <!-- Please describe your changes on the following line: --> --- <!-- 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 - [ ] These changes fix #__ (github issue number if applicable). <!-- Either: --> - [ ] There are tests for these changes OR - [x] These changes do not require tests because they do not change behavior, just fix a runtime warning. <!-- 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: 46f6e68bad7aafc380976bfddd9e76bfaa86229e --HG-- extra : subtree_source : https%3A//hg.mozilla.org/projects/converted-servo-linear extra : subtree_revision : de75e85a605eaa517b1a88afed60a541df8bba3f
