`react-stack-bottom-frame` -> `react_stack_bottom_frame`. This survives `@babel/plugin-transform-function-name`, but now frames will be displayed as `at Object.react_stack_bottom_frame (...)` in V8. Checks that were relying on exact function name match were updated to use either `.indexOf()` or `.includes()` For backwards compatibility, both React DevTools and Flight Client will look for both options. I am not so sure about the latter and if React version is locked.
