Bug description

There's 2 weird cases that can happen with breakdowns:

(1) On breakdown, the count increases

This happens when a person completes a funnel using multiple properties (ex: breakdown by browser, person completes funnel in Chrome and Firefox implies the count doubles)

(2) On breakdown, the count decreases

This happens because we have a limit on the number of breakdown properties to display. These properties are given in decreasing order of size, so smaller breakdown values might not show up, thus showing a slight discrepancy in numbers with & without breakdown

(3) Not-weird: On breakdown, the count remains the same

This happens when neither of the above conditions are met (breakdown values count is less than 10, and no person completes/enters the funnel using different breakdown values)

Expected

It would be nice to explain to users when there are inconsistencies, and why.
