Configuration:
- Web browser and its version: firefox nightly
- Operating system and its version: linux debian

Steps to reproduce the problem:
1. Open the PDF
2. Click on the button  `Rellenar Formulario` (top right of the first page)
3. There is the pop-up "Stay... or Leave...`.

It's a bit annoying from the user pov and it doesn't make sense (nobody wants to leave the form but just reset it)

It works fine when replacing  `""` by `"#"` here:

@Snuffleupagus, you changed this few month ago:

do you have some ideas ?
const borderWidth = data.borderStyle.width;
    const square = this.svgFactory.createElement("svg:rect");
    square.setAttribute("x", borderWidth / 2);
    square.setAttribute("y", borderWidth / 2);
    square.setAttribute("width", width - borderWidth);
    square.setAttribute("height", height - borderWidth);
    
    
    square.setAttribute("stroke-width", borderWidth || 1);
    square.setAttribute("stroke", "transparent");
    square.setAttribute("fill", "none");
    svg.appendChild(square);
    this.container.append(svg);
    
    
    this._createPopup(square, data);
    return this.container;
  }
}
class CircleAnnotationElement extends AnnotationElement {
  constructor(parameters) {
    const isRenderable = !!(
      parameters.data.hasPopup ||
      parameters.data.title ||
      parameters.data.contents
    );
    super(parameters, { isRenderable, ignoreBorder: true });
  }
  render() {
    this.container.className = "circleAnnotation";
