Store multiline in Yaml data file from a textarea form field

[masetto]

I have an error when I store a multiline from a textarea form field, because in Yaml data file the textarea field has stored without > or | and indentation for each row.
I suggest to modify line 6 of forms/data.txt.twig from:

{{- field.name ?? index }}: {{ string((value is iterable ? value|json_encode : value)) ~ "\r\n" }}

To:

{{- field.name ?? index }}: {{ string((value is iterable ? value|json_encode : ("\n" in value ? (">\r\n  " ~ value|replace({"\n": "\n  "})) : value))) ~ "\r\n" }}

Perhaps it is better to create a specific twig file to perform this.

Just found this here! Reported it and submitted a PR two days ago in form plugin repo.

Also seems a duplicate of old bug #2 here, which is closed for some reason.
