Newline removed when model gets updated [message #965544]

I am facing the following problem.
I want to implement a quick fix that does the following:
Imaging the following grammar:

Grammar: Item*;

Item: (label=STRING)? 'Token';

Now, under certain circonstances, my quickfix will add a label to Item that does not have a label. So it does it by updating the Item model and adding the label.
Now, imagine I have the following file content:

LABEL1 Token \n
Token\n

So when the second item gets updated with a new label, then it seems it gets inserted at the end of the previous Item, replacing whitespace characters, so I get:

LABEL1 TOKENLabel2 Token

Is there a way to change this behaviour ?
Thanks

The quickfix relies on the serializer to transform the changes on the
semantic model back to the text.

Which serializer fragment are u using in the workflow of your language?
Please make sure to use
fragment = serializer.SerializerFragment
and not the old
fragment = parseTreeConstructor.ParseTreeConstructorFragment

If you do already use the new one, it's a bug.

I checked my .mwe2 file and I'm using the new serializer fragment:

// Serializer 2.0
fragment = serializer.SerializerFragment {
generateStub = false
}

I will try to setup a sample project to demonstrate the problem and then open a bug
