But that happens all the time in video game code.

Video games may have many threads running, but there's usually a single-thread bottleneck. To the point that P-cores and massively huge Zen5 cores are so much better for video games.

Javascript (ie: rendering webpages) is single-threaded bound, which is probably why the Phone makers have focused so much on making bigger cores as well. Yes, there's plenty of opportunities for parallelism in web browsers and webpages. But most of the work is in the main Javascript thread called at the root.
