chore(monosize): externalize react/jsx-runtime for bundle-size config by Copilot · Pull Request #36222 · microsoft/fluentui

Copilot · 2026-05-19T09:02:46Z

Follow up #36198 (comment)

Inspect existing /home/runner/work/fluentui/fluentui/.github/CODEOWNERS ownership patterns
Confirm established build ownership pattern (**/project.json @microsoft/fluentui-react-build)
Run baseline checks before edit (build/test pass; lint has pre-existing missing eslint plugin module in this environment)
Add ownership rule for **/monosize.config.mjs to @microsoft/fluentui-react-build
Run post-change validation (build/test pass; lint unchanged pre-existing failure)
Run parallel validation (Code Review + CodeQL)
