Suspected YouTube bug spikes RAM over 7gbs users report lag and frozen tabs

I'm amazed by how bad web browsers are at handling web pages requests for too much RAM. I have an html files with just a one-line JavaScript command to create a 1 GiB array, that I open a few tabs of, whenever I need to stress test a computer:

    var allocation = new Array(1073741824).fill(0);

For an ecosystem that is so VM-heavy, I'm surprised there isn't a system like Linux cgroups, to limit the CPU and RAM usage of any given page.

I'm glad I'm not the only one, this was giving me big problems, with Firefox on my mac

I'd click on a youtube video, nothing would happen, and I'd tab over to my CPU monitor (which I kept running for just this purpose.) and I'd see the load up around 230%. I'd have to kill the process and usually give up on the video. It would only happen to some videos, but consistently the same ones. And I'd definitely see a problem with the buttons below the video - seemed like when the tab locked up sometimes the far right button would be rendered beneath the column on the right, like the reflow failed.

I haven't seen it happen again in the last few days.

bigquery studio will do this on a fresh page load.
