In Gecko, unlike other runnables where the TaskController picks one each at a time, the TimeoutManager allows multiple timers to run sequentially without allowing other runnables to run in between. This patch makes the user_blocking and user_visible tasks dispatched by Scheduler API can run before timers. Differential Revision: https://phabricator.services.mozilla.com/D237753
