Duplication of <script> section on page with Output controls

[sok82]

Description

Whenever I place Output control on page and rerender it - it creates additional <script> tags on page i.e. I see multiple

<script data-jupyter-widgets-cdn-only="true"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/require.js/2.3.6/require.min.js"></script>

elements on page and number of these elements multiplies after each page rerender

Reproduce

1. Place Output control inside Jupyter section on the page
2. Load the page
3. Check page source code with Developer console
4. See

<script data-jupyter-widgets-cdn-only="true"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/require.js/2.3.6/require.min.js"></script>

5. Initialize page rerender
6. See something like

<script data-jupyter-widgets-cdn-only="true"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/require.js/2.3.6/require.min.js"></script>
<script data-jupyter-widgets-cdn-only="true"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/require.js/2.3.6/require.min.js"></script>
<script data-jupyter-widgets-cdn-only="true"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/require.js/2.3.6/require.min.js"></script>
<script data-jupyter-widgets-cdn-only="true"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/require.js/2.3.6/require.min.js"></script>

which number (my guess) depends on number of Output controos
