*Steps to reproduce:*
# Create a new HDRP project
# Import Water Samples from the HDRP package samples
# Enable Water in the Quality > HDRP > Water
# Open a sample scene (e.g., "Rain")
# In the Hierarchy, click on the "Ocean" GameObject
# In the Inspector, select and expand a dropdown
# Observe the water behaviour in the Scene View

\\
*Actual results:* The water freezes/pauses when a dropdown is selected in the Inspector

*Expected results:* The water should continue moving even when a dropdown is expanded, similar to the behaviour seen when interacting with checkboxes and sliders

\\
*Reproducible with versions:* 6000.0.48f1, 6000.1.0f1, 6000.2.0a9

\\
*Tested on (OS):* Ubuntu 24

*Notes:* This behaviour is inconsistent with other Inspector UI elements; water should not pause unless a scene-affecting change is triggered
