Hello All,
This is kind of weird error and not sure if anyone has ever faced it before.
I am working on Personas 3.0 and its in initial phase, trying to create the flavors for credit memo.
In the flavor if I hide the status bar, save and exit then a loading symbol comes and the flavor doesn't get loaded at all.
Here are the screen shots.
Below you can see the loading symbol, here I have removed the status bar.
If check the console I see below error.
If I don't hide the status bar then there will not be any error and flavors load fine.
System details:
It took a while for me to figure out this issue, waiting for your inputs/suggestions/solutions 
Regards,
Karthikeya
