Inspired by #32950. Specifically from https://github.com/facebook/react/issues/32950#issuecomment-2837887871, it sounds like Babel by default emits source map information for all nodes, even when they don't have a `loc` property set. Code coverage tools then pick up the synthesized source location information for this, leading to the issue described. A few google searches didn't turn up any documented way to opt-out of generating source span information, but AI tools answer that explicitly setting `node.loc = null` omits the node from source maps. This PR is a quick hack to confirm that. [ghstack-poisoned]
