* Summary of `ReactBrowserEventEmitter` event handling:
|
|
*
|
|
* - Top-level delegation is used to trap most native browser events. This
|
|
* may only occur in the main thread and is the responsibility of
|
|
* ReactDOMEventListener, which is injected and can therefore support
|
|
* pluggable event sources. This is the only work that occurs in the main
|
|
* thread.
|
|
*
|
|
* - We normalize and de-duplicate events to account for browser quirks. This
|
|
* may be done in the worker thread.
|
|
*
|
|
* - Forward these native events (with the associated top-level type used to
|
|
* trap it) to `EventPluginHub`, which in turn will ask plugins if they want
|
|
* to extract any synthetic events.
|
|
*
|
|
* - The `EventPluginHub` will then process each event by annotating them with
|
|
* "dispatches", a sequence of listeners and IDs that care about that event.
|
|
*
|
|
* - The `EventPluginHub` then dispatches the events.

/**
|
|
* We listen for bubbled touch events on the document object.
|
|
*
|
|
* Firefox v8.01 (and possibly others) exhibited strange behavior when
|
|
* mounting `onmousemove` events at some node that was not the document
|
|
* element. The symptoms were that if your mouse is not moving over something
|
|
* contained within that mount point (for example on the background) the
|
|
* top-level listeners for `onmousemove` won't be called. However, if you
|

* catch all `mousemove`s. This along with iOS quirks, justifies restricting
|
|
* top-level listeners to the document object only, at least for these
|
|
* movement types of events and possibly all events.

|
*
|
|
* @see http://www.quirksmode.org/blog/archives/2010/09/click_event_del.html
