<!-- Please describe your changes on the following line: --> This makes it so each task is a thin wrapper over a runnable and whenever a task is queued, it is automatically wrapped by the window's `runnable_wrapper`. --- <!-- 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 #11703 (github issue number if applicable). <!-- Either: --> - [ ] 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: 3011d4b450b107f87fab54f6c59245ac1478fa79
