I created a pdf for https://github.com/mozilla/pdf.js/pull/14023:
[same_fields(1).pdf](https://github.com/mozilla/pdf.js/files/7168340/same_fields.1.pdf)
The 3 checkboxes have the same name (`Check Box2`) and have the same values (`Off` and `Yes`).
In pdf.js, these checkboxes behave like radio buttons in the same group (which is wrong) because of:
https://github.com/mozilla/pdf.js/commit/1fcffe80349a98378262c8a16f7b50ff34c3fe82
Since they've the same values they must be synced: if one is checked (resp. unchecked) then all others are checked (resp. unchecked).
if (baseName.includes("mouse")) {
      
      element.addEventListener(baseName, event => {
        this.linkService.eventBus?.dispatch("dispatcheventinsandbox", {
          source: this,
          detail: {
            id: this.data.id,
            name: eventName,
            value: valueGetter(event),
            shift: event.shiftKey,
            modifier: this._getKeyModifier(event),
          },
        });
      });
    } else {
      
      element.addEventListener(baseName, event => {
        this.linkService.eventBus?.dispatch("dispatcheventinsandbox", {
          source: this,
          detail: {
            id: this.data.id,
            name: eventName,
            value: event.target.checked,
          },
        });
      });
    }
  }
  _setEventListeners(element, names, getter) {
