*Steps to reproduce:*
# Open a Unity Project
# Add a new GameObject to the scene via GameObject > Create Empty
# Select the new GameObject and add a Line Renderer component via Add Component > Line Renderer
# In the Line Renderer component, ensure that the Positions section is expanded
# Click the arrow to collapse the Positions section

*Actual results:* The section slightly collapses (up to the point of the values of the table being mostly hidden) then it delays for a second before the rest of the section is collapsed.

*Expected results:* The section all collapses straight away without any delay.
