Currently the simple event plugin defines a priority for the event but not all events go through the SimpleEventPlugin. That's just one of several EventPlugins. The remaining ones now get the wrong priority associated with them. 

E.g. I think all of these should be discrete:

change
compositionend
compositionstart
compositionupdate
selectionchange
textinput

These show up too but I don't know if they're even bridged.

dblclick
pointerenter
pointerleave

Flare defines its own priorities.
