I can't believe that a competent developer can actually make a site that bad, unless they were doing so deliberately. The latest egregious www. bug is that videos with sound go silent after 2-3 seconds (desktop safari). I don't remember any time in the past when reddit's video player worked 100%, despite video being a solved problem for what, 10 years? So this isn't be a surprise. What's surprising is how bad their developers managed to make the product, and how it gets worse over time rather than better.
