I was testing the accuracy of setTimeout
using this test. Now I noticed that (as expected) setTimeout

I have released worker-interval npm package which setInterval and clearInterval implementation with using Web-Workers to keep up and running on inactive tabs for Chrome, Firefox and IE.
Most of the modern browsers (Chrome, Firefox and IE), intervals (window timers) are clamped to fire no more often than once per second in inactive tabs.
