*Steps to reproduce:*
# Create a new Unity project using Universal 3D template
# Create a new Particle system (GameObject > Effects > Particle System)
# Select the newly created Particle System in the Hierarchy window
# Click the "Open Editor..." button in the Inspector window
# Resize the window to be smaller or dock the window and resize
# Observe the "Optimize" and "Remove" buttons

*Actual results:* The "Optimize" and "Remove" buttons overlap with other UI elements

*Expected results:* No UI elements overlap

*Reproducible with versions:* 2021.3.51f1, 2022.3.62f1, 6000.0.49f1, 6000.1.3f1, 6000.2.0b1

*Tested on (OS):* macOS Silicon Sequoia 15.3

*Notes:*
* This is very noticeable when there are more Particle Systems and the Particle System slider is all the way to the right
* Very noticeable when the window is docked and smaller than the minimum width for undocked window
