Pipeline based decorator rules

Have messages with extremely long lines. Figured out the pipeline rule code (for a decorator) that will correctly break the line down into appropriate components. Currently, can do “\n” and can see that in the decorated field - the lines break on the correct point. However, cannot get the browser to appropriate interpret. eg: “\n” isn’t interpreted by the browser [expected] and using “
” (which is correct for HTML) isn’t working either. Thoughts?

Thanks!
