give javascript executing in background tabs less priority

for example, say I have something that does a ton of js in tab, but that tab is in a background tab or a minimized window.  can we give more priority to js in the chrome or in the currently focused tab?

brendan, would something like this even be possible?

Daniel, do you think this is a common enough problem to be tracked for snappy project? Is it possible that smaller/simpler SVGs also cause annoying stalls? Is this something that we can easily add telemetry probes for?
