RSRP-183038: Create local variable: Fails to determine type for enum if if-condition exist that compares variable with 0.

[5.1.1712]

public class Foo
{
  public enum enTest { One }
  public void Bar(enTest value)
  {
    testValue = value;
    if (testValue==0)
        throw new ArgumentException();
  }
}

Try create local variable 'testValue', this will suggest type "object".
If altering the if condition to...

if (testValue==enTest.One)

...the create local variable suggest proper type.
(Also works properly if removing the condition all together).
