Ignore, bad use of Trait

Hello,

Version: 0.16.18 Are you able to reproduce the bug from the demo? [X] Yes [ ] No

What is the expected behavior? Only add one trait, being able to test empty trait addition

Describe the bug detailed Adding trait with:

            const component = editor.getSelected();
            if (!component.getAttributes()['newtrait']) {
                component.addTrait('newtrait');
            }

Adds a new empty trait ... each time this component is selected:

Because getAttributes is undefined:

editor.getSelected().getAttributes()['newtrait']
undefined

Until I fill newtrait with a value and newtrait value exists. It still keeps all the duplicate fields:

Maybe I missed something? Or is it a bug? Thank you EDIT: fixed by setting a value to the trait afterward :) Obvious, sorry!
