False positive for experimental:indent with new line before return type

[lwasyl]

For the given function:

abstract fun doPerformSomeOperation(param: ALongParameter):
    SomeLongInterface<ALongParameter.InnerClass, SomeOtherClass>

and with both indent and continuation indent set to 4, KtLint reports at the second line that Unexpected indentation (8) (should be 4)

This seems to be a false positive, since some indent (normal or continuation one) should be applied for that line, otherwise we'd end up with

abstract fun doPerformSomeOperation(param: ALongParameter):
SomeLongInterface<ALongParameter.InnerClass, SomeOtherClass>
