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.
link.href = this.linkService.getDestinationHash(destination);
    link.onclick = () => {
      if (destination) {
        this.linkService.goToDestination(destination);
      }
      return false;
    };
    if (destination || destination ===  "") {
      link.className = "internalLink";
    }
  }
