A text block in the designer tab does not reflect the text within a variable that is used in a binding

When using a text variable as a binding for a text block, the text does not reflect the default value that is assigned to the variable that the text block in bound to. This can make it more difficult to working with the text block in the designer tab.

Note: the binding works as expected in game

1. Open Editor
2. Create a new widget blueprint
3. Add a text variable to the event graph
4. Name the variable "MyText"
5. Set the default value as "TextandStuff"
6. Add a text block to the designer tab
7. Bind the text for the text block to the text variable (MyText)
8. Compile and save
9. Notice that the text block still says "TextBlock"

Expected: The Textblock would update to the default value of the binding
Result: The Textblock maintains it's own default value
