Widget Compiler not saving a text field with only spaces

The UMG Editor's text component will not save the text field if it only contains spaces. This can hinder projects that need to get the distance of a space, as with the case linked with the Additional info URL.

1. open a new project
2. Create a new widget
3. add a text into the scene
4. in the details panel > Text > Clear the field
5. Press the space bar in the field
6. Compile the blueprint
   Results: The spaces are deleted and the field is empty
   Expected: The spaces are saved in the field
