When a user right-clicks on a host and then clicks on "Change Port Config", a popup opens that will cause some parts of the WebWriter UI to dim while others are still displayed in front of the popup (see screenshot below).

Steps to reproduce
- Right-click on any host in the editor
- Click on "Change Port Config"
- Observe the popup and surrounding UI
Expected behavior
The popup should either not leave the widget area or make sure that all background UI elements are properly dimmed and arranged behind the popup.
