How to properly listen to 'styleable:change' without also selecting the other components

[iamqinglong]

CODE:

view: {
    init() {
        this.listenTo(this.em, `styleable:change`, (args, property) => {
          console.log(args,property)
        })
      }
}

I have two buttons

But when I tried to changed the styling (ex: border-radius) of first button, the 2nd button component also listen to the
style changes
