*Steps to reproduce:*
# Create a new Unity project using the Universal 3D template
# Install the Visual Effect Graph package
# Create a new Visual Effect Graph (Assets > Create > Visual Effects > Visual Effect Graph)
# Select "Simple Loop" Visual Effect Template
# Open the created Visual Effect Graph
# Click anywhere in the Visual Effect Graph window and press spacebar
# Keep repeating step 6 but clicking in a different spot each time
# Observe the Visual Effect Graph window

*Actual results:* There are multiple/many node creation windows all over the Visual Effect Graph window

*Expected results:* Every time the user clicks somewhere outside the node creation window, the node creation window should disappear to prevent multiple node creation windows appearing on the screen

*Reproducible with versions:* 6000.3.0a3

*Not reproducible with versions:* 6000.0.54f1, 6000.1.13f1, 6000.2.0b11, 6000.3.0a2

*Tested on (OS):* macOS Silicon Sequoia 15.5 (reproduces), Windows 11 (does not reproduce)

*Notes:*
* Even after restarting the Editor, the node creation windows remain
* This operation cannot be cancelled by left-click on the empty workspace, you must select a node to remove the node search
* You can close VFX window and the node search is gonna be visible
* Also reproducible with Shadergraph
