Dropdown menus are rendered outside Shadow DOM

[gnugomez]

As you will be able to see in the screenshot, the font/colors of the site gets somewhat leaked to the dropdown UI.

I did some debugging and see that your actually what's happening is that this dropdown menus are being rendered outside the main Shadow DOM of the studio that would prevent that from happening.

This can be fixed by using portal: false: b5ac204

But we need to fix dropdown position.
