Kai,

Due to the way the code is generated by the V8 compiler, some optimizations 
cause some 
statements to be non-breakable.
You will find the same kind of behaviour in the built-in Google Chrome DevTools.

Please feel free to file an issue against V8 if it is necessary for you to be 
able to 
break on similar "reduced" statements.
