What does flamethrower do? Without the library, the server island works, so @futamiy you would need to explain to us at least what's happening.

I don't think there's much we can do, if a library messes up with script tags, we can't prevent it.

I will send a PR to avoid that runtime error in the console, but maybe you should check if that library allows to prevent prefetching all script tags
