<!-- Please describe your changes on the following line: --> r? jdm Moved the following functions from components/script/dom/bindings/interface.rs to a new file components/script/dom/bindings/htmlconstructor.rs: - html_constructor() - get_constructor_object_from_local_name() - pop_current_element_queue() - push_new_element_queue() --- <!-- 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 #19179. <!-- Either: --> - [X] These changes do not require tests <!-- 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: 07fd6155aae8579f1a30ea99af3549c413240f24 --HG-- extra : subtree_source : https%3A//hg.mozilla.org/projects/converted-servo-linear extra : subtree_revision : 28bc09e28368565f2f4050676e233ff133fb9407
