The histogram 'GPU.ContextLost.BrowserWorker' is present in Chromium source
code but does not appear in histograms.xml. This means that data is collected
for the histogram but nothing useful is done with it.

The histogram was defined in
content/common/gpu/client/command_buffer_metrics.cc at line 89.

https://cs.chromium.org/chromium/src/content/common/gpu/client/command_buffer_metrics.cc?l=89

It may have moved by the time you read this.

Please remove the histogram 'GPU.ContextLost.BrowserWorker' from the source
code. If it was very recently added, it may be worth adding it to
histograms.xml instead, but probably not.

This bug was automatically assigned based on git blame information. If you
are not the correct assignee for this bug, please delete the histogram
anyway.
