<!-- Please describe your changes on the following line: --> At the moment, a webdriver session stores a `pipeline_id`s, which causes a mismatch with the spec, which asks a session to store a browsing context and a top-level browsing context. This PR fixes this mismatch. --- <!-- 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 do not require tests because we are not testing webdriver <!-- 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: 0bc7e2fddf51d43c6c135d95ab9c9a8a08756ffb --HG-- extra : subtree_source : https%3A//hg.mozilla.org/projects/converted-servo-linear extra : subtree_revision : 182f660ea11c684bb880cc94c6304d397ee56c2d
