Summary: Changelog: [internal] This is a mechanism that will guess event's React priority based on other events ongoing on the platform. If an event happens within span of ContinuousStart -> ContinuousEnd and its category is unspecified, we deduce it's React priority to be default. All other events are discrete. Special case: `onScroll`, which is always treated as "Default". Reviewed By: JoshuaGross Differential Revision: D28485060 fbshipit-source-id: d2eae63dbcf03271dfed97128a1590dd165a3ce2
