*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
# Press the + button in the blackboard
# Select Attribute > Float
# Enter a very long name and press enter
# Observe the Editor

*Actual results:* Editor hangs and becomes unresponsive indefinitely

*Expected results:* The attribute is created or a warning/error appears that the attribute name has too many characters

*Reproducible with versions:* 6000.0.54f1, 6000.1.13f1, 6000.2.0b11, 6000.3.0a3

*Tested on (OS):* Windows 11, macOS Silicon Sequoia 15.5

*Notes:*
* On Windows 11, the Editor sometimes doesn't hang but starts loading/recompiling upon every mouse click or even the mouse moving, becomes extremely slow
* On Windows 11, sometimes after step 8, have to click the arrow button next to the name to expand the Attribute, that results in 100% reproduction in either Editor hanging or getting into a recompile/loading loop
* On Mac, the Editor always hangs and becomes unresponsive needing to Force Quit which results in data loss
