What:

Fix stack overflow error in React 19 caused by deepmerge attempting to merge children props. Fixes: #476

Why:

The library was crashing with "RangeError: Maximum call stack size exceeded" when used with Next.js 15 and React 19. This occurred because the WithStore HOC was trying to deepmerge this.props.children, which contains React elements with circular references that cause infinite recursion during the merge process.

How:

Modified the render() method in WithStore.jsx to extract children from props before passing the remaining props to deepMerge. The children are then passed directly to the wrapped component, avoiding the circular reference issue while maintaining the same functionality.
