/// Regression test for http://dartbug/28196

/// The constructor of a mixin application of a subclass of a Html element is
/// normally not used. With mirrors the constructor can become available. The
/// body of the factory has a 'receiver' with an exact type that is the mixin
/// application. The constructor body functions of the superclasses are called
/// using the interceptor calling convention. This creates an interceptor
/// constant of the mixin application type.  In issue 28196 the constant has a
/// name containing '+' symbols, causing the program to crash during
/// initializing the constant pool.
