Simon, this looks like a different bisect failure result now. Do you mind taking a look?
Hit the 24 hour limit. I'll rekick this with the narrowed range.

Build failures prevented the bisect from narrowing the range further.

Summary: loading.mobile failing on Nexus 5X perf bot (was: loading.mobile failing on 3 builders)
Nexus 9 bots are gone.
The A1 bots seem to have gotten better.
The 5X bot seems to have gotten better then broke again recently. Kicking off bisect for it. Renaming to reflect reality.
