Will the browser remember the HTMLInputElement state when move Widget to other place?
1. Write some in Widget input.
Then the Widget will move from `.div1` to `.div2' using `ChildNode.after()`.
2. Use Ctrl+Z keyboard shortcut to undo.
In Firefox - you can not undo the first letter.
In Chrome - you can.
That also applies to `ChildNode.after()`, `Node.appendChild()` etc.
