Hi!

I'd like to report that running Jest tests in parallel might cause some unintended timeouts caused by cpu/request throttling by Chromium. Furthermore, it is totally random because which tab is active in chromium when running parallel tests is random by race condition.

Further explanation of the phenomenon: https://blog.bigbinary.com/2018/08/15/debugging-failing-tests-in-background-tab-in-puppeteer.html

Maybe add this flag to the preset?
