ICS file opened using Microsoft Outlook Desktop 2016's Calendar not honoring new lines in the Description body

Question

As title states, when the ICS file below is opened using Microsoft Outlook Desktop 2016's calendar, the second to last new line (the "\n" before "lectus") in the Description body is not honored. The word "lectus" remains on the same line as the text before it when the event is opened in Outlook's calendar. This is obviously a contrived example but we are encountering this issue with other files. The new lines are working fine, however, when using outlook web, yahoo calendar, and google calendar. The file below is valid according to https://icalendar.org/validator.html.

Is anyone aware of a bug in Outlook 2016 desktop or am I missing something in the formatting of the file?

Thanks in advance.

I included a snapshot below of what I'm talking about. Notice the word "lectus" does not start on a new line.

The validators are not perfect or all encompassing. Try check against as many as you can. eg http://ical-validator.herokuapp.com/?wicket:interface=:1:::: says

! CRLF should be used for newlines Related RFC 5545 section: 3.1

CRLF is \r\n (not \n\r) https://developer.mozilla.org/en-US/docs/Glossary/CRLF
