`becomeDirty()` Seems To Be Throwing Some Errors In Ember-2.x

[nadnoslen]

"Error: Assertion Failed: You modified "value" twice on <valet@component:-text-field::ember1671> in a single render. It was rendered in "component:-text-field" and modified in "component:-text-field". This was unreliable and slow in Ember 1.x and is no longer supported. See https://github.com/emberjs/ember.js/issues/13948 for more details.

I noticed this happening when we toggle a select boxes value for a model's relationship. Triggering the option choice from the select box also calls the model's becomeDirty() function. Once the model is saved, this error is presented in the console.
