What happens when you set a session-scope custom dimension more than once in the same session?
Simple question for ya.
EDIT: In case it wasn't clear... suppose you have a session-scope custom dimension, defined by:
name: my_custom_dimension
index: 1
scope: Session
and then do
ga('set', 'dimension1', 'LOL');
and then in the same session do
ga('set', 'dimension1', 'LMAO');
what will the reports show is the value of dimension1 for that session?
