CAN_PERSIST_ACTIVITY_EVENTS parsing conflict with outputHeight

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Set the optional outputHeight field in a .js file
2. Turn on CAN_PERSIST_ACTIVITY_EVENTS (set True in utils.py)
3. Visit the Activity

What is the expected output? What do you see instead?
I'd expect the .py parser to parse outputHeight fine.  Instead it crashes when 
py tries to parse the .js Activity.

What version of the product are you using? On what operating system?
1.5.0 on GAE 1.8.1

Please provide any additional information below.
I can fix this by never using outputHeight (no biggy), but I wanted to let you 
know their is a bug.  Here is the Trace...
