\r\n being interpreted as a vertical tab during Export

Description
\r\n being interpreted as a vertical tab during Export.

How to reproduce

1. Create a set function with the following parameters ${set(sep, "\r\n")}
2. Concat that set with a another mapping
   Used template:
   testing vertical tab.xlsx

Actual result/Attachments
The summaries of the issues will show up together with a vertical tab
The problem is regarding the \r\n that is considered as a vertical tab when exported:

Expected result
No vertical tabs should be shown, and the template must be clean of that

UPDATE:

• This is also happening with the JS ReplaceAll fuction
• This seems to happen when the String containing the "\r\n" is following an If or For statement that results in blank or empty
• If the String is printed without any other functions, the "\r\n" work as a line jump, as expected, and the Vertical Tabs [] do not show in the report.
