This commit was originally automatically generated using `tools/lint --only=eslint --fix`. It was then modified by tabbott to contain only changes to a set of files that are unlikely to result in significant merge conflicts with any open pull request, excluding about 20 files. His plan is to merge the remaining changes with more precise care, potentially involving merging parts of conflicting pull requests before running the `eslint --fix` operation.
