Clicking a Blueprint Window After Entering a Variable Tooltip Discards the Changes

Changes made to a blueprint variable's tooltip are discarded when clicking in the main blueprint viewport (Event Graph, Function Graphs, etc). Clicking in the variable's details panel does save the changes, so the behavior is inconsistent.

1. Open the editor
2. Create a new actor blueprint
3. Create a new variable
4. Enter a tooltip for it in the details panel (Do not press Enter to confirm the tooltip)
5. Click in the Event Graph window

Result: Tooltip changes are discarded

Expected: Tooltip changes would be entered.
