Repro steps:
1. Open blackboard within a VFX
2. Create a new category
3. Press F2 or double-click on the category to rename it
4. Try clicking away and observe how the rename is still active

Expected outcome:
- The rename to stop once the user clicks away

Notes:
- The issue is probably that the rename field is not highlighted when renaming is triggered (unlike the parameter renaming)
- Highlighting the field and clicking away works as expected
