I'm seeing this with Chrome and Firefox on Windows 10.
Recreation procedure:
1) Open [https://forums.garmin.com/developer/connect-iq/i/bug-reports/assorted-media-player-button-bugs-across-devices?CommentId=76df4e23-19d0-4c7a-a875-f5f9a7ea7ab2] (This was linked from another bug report: https://forums.garmin.com/developer/connect-iq/i/bug-reports/media-player-bugs)
2) Scroll to bottom
3) Click on "View More" at the bottom of the page
4) Scroll to bottom again
5) Enjoy endless cascade of pseudo-notifications proclaiming "There are no remaining comments", until you scroll up
See: https://postimg.cc/qhP6cRf6
Note that this does not happen when you navigate to the bug report normally. (In that case, you won't see more than 5 comments unless you click on "Oldest" or "Newest")
Not to mention the fact that it's weird that both the middle and the end of the comments have a "View More" button. (Sorry, but there are other far superior modern forum platforms, like Discourse or NodeBB, which have the ability to instantly jump to any point in a discussion with 1000s of comments with no problem on either desktop or mobile while still supporting infinite scroll -- I still don't get why this is the one that was chosen.)
