${wiki:} on Comment Body Produces Excessive Blank Lines in XLSX Output

Description

When exporting comment bodies via `${wiki:}` in an XLSX template, paragraph breaks render with extra newlines in the output Excel cells, which produces excessive blank lines between paragraphs.

Used template: Test_Comment.xlsx

How to reproduce

1. Create an issue.

2. Add a comment containing multiple paragraphs.

3. Create a template to export the field with the Wiki markup.

4. Run the export via Xporter.

Actual result/Attachments

Comment body cells in the exported XLSX contain extra newlines between paragraphs, with visible excess whitespace in the output. 

Expected result

The comment body should retain its original formatting and spacing, with paragraph breaks rendered consistently without introducing extra whitespace.

Version

• Xporter Cloud 6.0.0

Workaround

Removing the wiki: prefix from the mapping will ensure the newlines render correctly, but the field output will lose any wiki-markup styling configured in the comment.
