Although I'm not sure what you're motivation for this behavior is, your logic is even possible with Vanilla JS:

• Simplest way to detect keypresses in javascript
• Is it possible to simulate key press events programmatically?

Minimal example for your use case:

• Click into the input field
• Now press tab
• You will see an alert that tab was pressed
• Immediately after, you will see that enter was pressed as well (programmatically)

let element = document.querySelector('input');
element.onkeydown = e => {
  alert('key pressed: ' + e.key);
  if (e.key === 'Tab') {
    element.dispatchEvent(
      new KeyboardEvent('keydown', {
        'key': 'enter'
      }));
  }
}

<input/>
