TextField value change in Chrome

Vaadin 6 / 7 / 8 Framework UI
1

In my vaadin13 project I use TextField. When enter key is pressed the TextField’s value is changed programmatically
Everything works fine in IE browser.

But when I use Korean characters and press enter key they do not work in Chrome browser.
How can I change value in Chrome browser.

I have the following Source:

[ CD01View.class ]

@Tag("cd-01-view")
@HtmlImport("cd-01-view.html")
@Setter
@Getter
public class CD01View extends PolymerTemplate<CD01View.CD01ViewModel> {

    @Id("companyName")
    private TextField companyName;

    public interface CD01ViewModel extends TemplateModel{    
    }

    public CD01View(){
        this.companyName.setValueChangeMode(ValueChangeMode.EAGER);
        this.companyName.addKeyUpListener(e -> { 
            if( e.getKey().getKeys().equals(Key.ENTER.getKeys()) ){   
                //When use Korean characters and press enter key next line do not work.
                this.companyName.setValue("aaaaaaaaa");
            }
        });
    }
}

[ cd-01-view.html ]

<!DOCTYPE html>
.....
<dom-module id="cd-01-view">
    <template>
        <style> .... </style>
        <div>

            <vaadin-text-field label="회사명" id="companyName"></vaadin-text-field>

        </div>
    </template>
    ....
</dom-module>
</html>
