*Steps to reproduce:*
# Create a new Unity project using the Universal 3D template
# Install the Visual Effect Graph package (com.unity.visualeffectgraph)
# Create a new Visual Effect GameObject (GameObject > Visual Effects > Visual Effect)
# Create a new Visual Effect Graph by clicking the "New" button under the Visual Effect component in the Inspector window
# Select "Simple Loop" and click the "Create" button
# Change the "Asset Template" in the Visual Effect component to "None"
# Observe the Attach button in the Visual Effect Graph window

*Actual results:* The Attach button in the toolbar is colored as if it is active and the tooltip says "Attached to Visual Effect" instead of "Select a Game Object running this VFX to attach it"

*Expected results:* The Attach button in the toolbar is no longer active and the tooltip is "Select a Game Object running this VFX to attach it"

*Reproducible with versions:* 6000.0.54f1, 6000.1.16f1, 6000.2.0f1, 6000.3.0a4

*Tested on (OS):* macOS Silicon Sequoia 15.5

*Notes:*
* If the GameObject is deleted, works as intended and shows as detached
