UI styling bug report

Not really a "site help" post, just reporting this case that _might_ be a bug in the comment thread section.

If user's avatar/profile image is in portrait orientation (taller than it's wide), it's not cropped into a square. If someone has eg. 100 x 800px avatar, it would stretch the comment container height and make the layout look funny.

Example: comment by A. B in https://www.fitnessblender.com/videos/lower-body-workout-with-kelli-and-daniel-40-minute-at-home-butt-and-thigh-workout

(You folks can probably tell i'm trying to procrastinate from doing that exercise by filing this bug report!! 🙈)
