Merge props function mutates given object.

I suppose this could be intended behavior, but if it is, I think it shouldn't be.

I was writing some stories for my vue storybook and ran into an instance where I was iterating over different variations of a component like so:

render() {
    types = [...blah];
    types.map(t => {
        const data = { attrs: { types[t]: true } };
        <ProfilePic {...data} />
        <ProfilePic url={picUrl} {...data} />
    }
}

I was getting odd behavior on the second component, and I managed to track it down to the fact that the data object is actually mutated in the creation of the first element. All the props are removed from the data object when props are "extracted" and applied to the element.

Is this intended behavior? or a bug? It seems like the data object to be merged should be cloned instead of mutated, but let me know if there's a reason for this. I can create a repro code pen if needed.

I don't think the issue is from this package. The implementation does not perform any mutations here.
