# Create a 2D/3D URP project
# Add any object in the "Hierarchy" window
# Select it and make a right-click
# In the contextual menu search input field enter "aa"
# Observe the window
# Add an additional "a" to the search
# And again observe the window

Expected Result: Window size always should be adjusted to the results list.

Actual Result: The window stays big/high after step 4 even it is empty. Added screenshots and video in the "Attachments" section.
