Steps to reproduce:

1. Create and open an empty project
2. Install com.unity.behavior
3. Create and open a behavior graph (Assets > Create > Behavior > Behavior Graph)
4. Right-click on an empty area and add a "Set Variable Value" node
5. Create a blackboard Vector3 variable
6. Assign the created Vector3 variable to the first variable of the Set Variable Value node
7. Click on the X field on the node
8. Type '1' and DON'T EXIT TYPING
9. Click on the Y field on the node

Actual results: The Y field is not highlighted and you have to click it again to type in the value

Expected results: The Y field is highlighted and accepts inputs

Reproducible with versions: 1.0.6

Not reproducible with versions: 

Can’t test with versions: 1.0.0 (in this version you can't type into the input fields on the node at all)

Tested on (OS): MacOS (M1) 15.1.1

Notes:

• This also applies to the inspector floating panel of the graph
• On the Blackboard floating panel, it works as expected (see video)
