Chrome draws border around Checkbox and RadioButton

[theJian]

For Checkbox and RadioButton that are initially in the Off state, Chrome draws thin borders around them. Those border will then disappear if I clicks on them. I suppose those fields should not have border around them.

/* global jsPDF */
var doc = new jsPDF();
var {
  ComboBox,
  ListBox,
  CheckBox,
  PushButton,
  TextField,
  PasswordField,
  RadioButton,
  Appearance
} = jsPDF.AcroForm;

doc.setFontSize(12);


doc.text("CheckBox:", 10, 125);
var checkBox = new CheckBox();
checkBox.fieldName = "CheckBox1";
checkBox.Rect = [50, 120, 30, 10];
doc.addField(checkBox);
checkBox.appearanceState = 'Off'


doc.text("RadioGroup:", 50, 135);
var radioGroup = new RadioButton();
radioGroup.value = "Test";
radioGroup.Subtype = "Form";

doc.addField(radioGroup);

var radioButton1 = radioGroup.createOption("Test");
radioButton1.Rect = [50, 140, 30, 10];
radioButton1.AS = "/Test";

var radioButton2 = radioGroup.createOption("Test2");
radioButton2.Rect = [50, 150, 30, 10];

var radioButton3 = radioGroup.createOption("Test3");
radioButton3.Rect = [50, 160, 20, 10];

radioGroup.setAppearance(Appearance.RadioButton.Cross);
