Eric Badger updated TEZ-4242:
-----------------------------
    Description: 
I went into "inspect" mode on my Google Chrome browser and in the Network tab I 
saw that {{TEZ_DAG_ID}} is getting loaded multiple times. Here is some of the 
double/triple loading that I saw take place. I've sanitized the urls so it 
looks kind of weird.

In our setup, we have both the counters and dagPlan in both {{TEZ_DAG_ID}} and 
{{TEZ_DAG_EXTRA_INFO}} as a local patch. However I've been testing around with 
a UI that has removed those and I still see the double/triple loading.
