What is the difference between the constants PLUGIN\_MIN(MAX)\_WIDTH(HEIGHT) and calling IPlugEditorDelegate::SetSizeConstraints?

My main concern is that when I resize the window below PLUG\_WIDTH or PLUG\_HEIGHT, the UI correctly resizes but the host (Reaper) shows scrollbars that scroll into white, outside of the bounds of GetBounds().

Edit:  
I also tried in FL Studio. Instead of showing scrollbars, it forbids resizing any dimension below the PLUG\_WIDTH/HEIGHT, even if PLUG\_MIN\_WIDTH/HEIGHT is much less.

Update: This happened because I was using IEditorDelegate::SetSizeConstraints().  
With PLUG\_MIN\_WIDTH/HEIGHT only, it works properly.
