Issue 2:
Describe what you were doing when the bug occurred:

I was using the devtools to investigate some performance issues w/ an app I help maintain

I had just turned on the "Record why each component rendered while profiling" checkbox

I ran a profile while navigating on the underlying page

The react profiler tab in the devtools gave this error, I think as I clicked the record icon to stop recording the profile.
