The spec says It is a compile-time error unless D is a function declaration. Nothing about a getter.

/**
 * @assertion It is a run time error if S does not declare or export either:
 * • A top-level function named main, or
 * • A top-level getter named main that returns a function.
 * @description Checks that it is not a runtime error if S declares a top-level
 * getter named main, returning function.

var x = 1;
get main => () { Expect.equals(1, x); };

Right; dart-lang/language#1248 clarifies that it is a compile-time error if main is a top-level getter. This was the intention already, but 'function' in the language specification is defined to refer to getters, setters, constructors, and "actual functions" (where the latter has a <formalParameterPart>). So this test should be adjusted to expect an error.
