I didn't try to reproduce multiple times since that would cause spam comments but it's most probably reproducable and independent of browser/OS.
Steps to reproduce the problem
Comment a URL without using markdown's hyperlink feature (e.g. "https://utopian.io")
What is the expected behavior?
In your @{username}/comments page you should see that URL in a non-hyperlink state.
What went wrong?
The URL in the comment got removed from @{username}/comments page.
Existing example from one of my comments
There is a URL (https://dmania.lol) in the comment below this post https://steemit.com/books/@fingolfin/2muszv-fantasy-book-recommendations
URL is not visible when comment is seen from my profile https://steemit.com/@taylan/comments
