Steps to reproduce the problem:
1. Write something in a field

What is the expected behavior? (add screenshot)
The 3 fields must have the same value

What went wrong? (add screenshot)
The 2 other fields are empty

The three fields share the same name `Text3`.
It works as expected in Adobe and Chrome.
constructor(parameters) {
    const isRenderable = !!(
      parameters.data.hasPopup ||
      parameters.data.title ||
      parameters.data.contents
    );
    super(parameters, { isRenderable, ignoreBorder: true });
  }
  render() {
    this.container.className = "squareAnnotation";
    
    
    
    const data = this.data;
    const width = data.rect[2] - data.rect[0];
    const height = data.rect[3] - data.rect[1];
    const svg = this.svgFactory.create(width, height);
