Can you describe this change a bit more? Do you know why we might have initially wanted it? Depending on my understanding of what's happening here, I don't think we probably need to do a full API review circuit here cc @electron/wg-api

This is splitted from #45539. Initially, OSR can't avoid copy texture from GPU to CPU (GPU accelerated mode), or CPU rendering (CPU mode), so it can't really goes beyond 240 fps because of the overhead. So I think its reasonable to set a 240 fps limit there.

As we now have shared texture OSR, it just copy GPU handle, and almost have no overhead. I think it is better to remove the limit in that case because it can goes easily beyond 240.

I tagged as semver/patch to avoid requiring the full API review. The change is also small enough, but lmk if others disagree with this decision.
