Crash a single page or even the whole browser isn't really a security problem though. In fact, there are so many ways to freeze the whole tab or even browser ui with build-in function if you apply it way too many times. (For example, a long chain of blur filters will make the chrome ui non responsive because the render time will skyrocket.)

Although if the affect area does escape the tab, the issue will have higher priority because that would be annoying to user.
