[Bug]: attrs json object in heading does not have Object prototype

What’s the bug you are facing?

Looks like attrs object (e.g. {level: 1} in my case) does not have Object as it's prototype and as a result calling attrs.hasOwnProperty will throw exception.

I created an issue in their repo but I think this should be fixed on both sides. There could be many more such cases.

This issue is critical for my app so if they won't fix it it would be awesome if you will. Please help. Thank u!
