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.
const { data, linkService } = this;
    const link = document.createElement("a");
    if (data.url) {
      addLinkAttributes(link, {
        url: data.url,
        target: data.newWindow
          ? LinkTarget.BLANK
          : linkService.externalLinkTarget,
        rel: linkService.externalLinkRel,
        enabled: linkService.externalLinkEnabled,
      });
    } else if (data.action) {
      this._bindNamedAction(link, data.action);
    } else if (data.dest) {
      this._bindLink(link, data.dest);
    } else if (
      data.actions &&
      (data.actions.Action ||
        data.actions["Mouse Up"] ||
