<!-- Please describe your changes on the following line: --> This PR allows different `Window` objects in the same browsing context to share a `BrowsingContext` object. SpiderMonkey requires a `WindowProxy` object to be in the same compartment as its `Window`, so when a `WindowProxy` changes `Window`, we have to brain-transplant it. In turn this requires the reflector of a `BrowsingContext` to be mutable. --- <!-- 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 #13608 and #14843 - [X] These changes do not require tests because an existing test catches this (`/html/browsers/the-window-object/Window-document.html` is now `PASS`) <!-- 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: 67c182638253211553161495cd2e4570002fd5bc
