1101171 - Profiler hangs on refresh sometimes

Status: RESOLVED WORKSFORME

(DevTools :: Performance Tools (Profiler/Timeline), defect)

Description

[Jordan Santell [:jsantell] [@jsantell]]

When recording with the Profiler, and refreshing the page and then stopping, about half the time, I get the following error, and the tool just waits on "loading" the information forever. 

A promise chain failed to handle a rejection. Did you forget to '.catch', or did you forget to 'return'?

I fixed this for a test failure.
