check here for some basic examples. eg. it can be used to leak info from one context to another.
there’s ofc legit uses for it too, which is why i argue for user intervention.
chromium based browsers behave like that if I’m not mistaken
i may be wrong? but my understanding is they’ll currently limit resources, but execution still takes place? that’s definitely useful, but my argument is for for an option where CPU resources be limited to 0 in background (without user intervention).
