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.
selEnd: event.target.selectionEnd,
              },
            });
          }
          _blurListener(event);
        });
        element.addEventListener("mousedown", event => {
          elementData.beforeInputValue = event.target.value;
          elementData.beforeInputSelectionRange = null;
        });
        element.addEventListener("keyup", event => {
          
          if (event.target.selectionStart === event.target.selectionEnd) {
            elementData.beforeInputSelectionRange = null;
          }
        });
        element.addEventListener("select", event => {
          elementData.beforeInputSelectionRange = [
            event.target.selectionStart,
            event.target.selectionEnd,
          ];
        });
        if (this.data.actions?.Keystroke) {
          
          
          element.addEventListener("input", event => {
            let selStart = -1;
            let selEnd = -1;
            if (elementData.beforeInputSelectionRange) {
              [selStart, selEnd] = elementData.beforeInputSelectionRange;
