*Steps to reproduce:*
# Create a new Unity project using the Universal 3D template
# Open the Rendering Debugger window (Window > Analysis > Rendering Debugger)
# Maximize the Rendering Debugger window
# Click and drag the slider in the middle all the way to the right until the slider disappears
# Observe the Rendering Debugger window

*Actual results:* There is no minimum width for the sections in the window and the user can drag the slider all the way to the edge making it disappear and uninteractable

*Expected results:* There is a minimum width for the sections in the window and the user cannot drag the slider all the way

*Reproducible with versions:* 2021.3.51f1, 2022.3.62f1, 6000.0.49f1, 6000.1.4f1, 

6000.2.0b2

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

*Notes:*
* There is no way to get the right section back since the slider is at the edge and uninteractable making that section of the window uninteractable as well, cannot change properties or settings
* The workaround is to reopen the Editor/project, reopening the window does not fix it
