sorry, one more thing I'm noticing now. You have these 3 seperate histograms for
tracking what happens on the Infobar. Normally in this pattern we have one
histogram, with an enum for each option - this way it is easy to see, say, the %
of Ignored.

Is there a particular reason you wanted seperate histograms for the 3 options?
Looks like historically it was this way, but looks to me like it would be
cleaner putting in one histogram. Let me know if I am missing something.
