The rootTag is used to use the context associated to the tag as part of the calculation of layout, otherwise it just uses the ReactApplicationContext. This diff unifies both method into an unique method that changelog: [internal] Reviewed By: JoshuaGross Differential Revision: D20081281 fbshipit-source-id: b1f6a6cedbf78f36f36fd0f93407c23c6996d76b
