…compliant downlevel class properties The build optimizer's static class field pass will now additionally wrap classes that contain side effect free class properties. This allows optimizers and bundlers further along in the build pipeline to downlevel that class properties while still retaining the ability to tree-shake the class if unused. The class properties may need to be downleveled for a variety of reasons such as lack of browser support, browser bugs with certain code structures, or to ensure spec-compliant runtime behavior.
