FIX. RadCollapsiblePanel - аfter restarting the application and reopening the designer several times, the inner controls shrink
DECLINED: caused by the fact the form has been edited under different DPI settings.
Workaround: specify the MinimumSize property at run time.

The issue is present because the form at hand was edited in the Visual Studio designer on a system with higher DPI settings. This caused the following line of code to be serialized in the Designer.cs file:
this.AutoScaleDimensions = new System.Drawing.SizeF(10F, 20F);
Deleting this line or setting the values to the standard ones (6F, 13F) resolves the issue.
