Listing last X runs for a specific product often shows <<X runs

[stephenmcgruer]

Example: right now, https://wpt.fyi/runs?label=master&label=stable&max-count=100&from=2020-10-12T00%3A00&product=safari shows ~15 runs. This is because, I assume, we first filter for the last 100 runs and then filter for Safari Stable.

Could we switch this round so that the max-count filter is considered after other filters? Would that be too expensive?
