Flickering when using the option Draw at desired size for widget components

Widget components that use draw at desired size appear to flicker when updating their size.

1. Download the attached project
2. Open the project
3. Play in editor
4. Click the texbox on screen
5. Hold down a letter on the key board (this will change the size of the widget component see gif)

Result: The widget component will flicker while it updates its size to accommodate the changes to the widget size
Expected: The widget would update its size without flickering
