These just add a bunch of noise to the data because they break some of the assumptions we have.

Avoid accumulating telemetry for size decodes

r=me, but can we clear the existing telemetry data before we land this, so the histogram isn't further muddled?

Taras, how would we go about invalidating the existing data for this histogram?

In this case, I don't think we need to invalidate the data because we're not doing size decodes yet because decode on draw is not on. Still, I'm interested in the answer.

Would it be useful to measure it but measure it separately?
