Describe the bug

How to reproduce the bug?

1. Create a element
2. set data-gjs-traits attribute to any default trait name like id or title, it will crush the whole thing

What is the expected behavior? I expect the same result as the data-gjs-traits='' which is setting traits empty

What is the current behavior? If I will place there something else than empty string it will crush the grapes

If is necessary to execute some code in order to reproduce the bug, paste it here below:
