*Steps to reproduce:*
# Open a Unity Project
# Create a new Animator Controller via Assets > Create > Animation > Animator Controller
# Open the new Animator Controller in the Animator Window by double clicking on it
# Right-click on the graph and create a New Blend Tree
# Double click on the created Blend Tree node to open it
# Observe that the initial node has a circular Slider Handle and it's default value is 0
# Select the initial node and add two Motion Fields to the Motion section in the Inspector
# Uncheck 'Automate Thresholds'
# Set the minimum Threshold (topmost Motion) to be higher than the value on the Slider (e.g. 0.2)

*Actual results:* The circular Slider Handle disappears. The value on the Slider is outside of the allowed range of values by the Motion Thesholds

*Expected results:* The circular Slider Handle remains. The value on the Slider is clamped to the range of values allowed by the Motion Thesholds
