Status: WontFix (was: Untriaged)
WontFixing this as it is recovered.

But kicked off several more bisects so we can tell what the cause was.

Also cc-ing perezju since this was so widespread (hundreds of regressions), in case he thinks it warrants re-opening.

Filed https://github.com/catapult-project/catapult/issues/4195 for Pinpoint being unable to find the webview metric.

The build errors were fixed in https://github.com/catapult-project/catapult/issues/4177, in case you want to try re-running any non-webview ones.
