@ryanbr If you see any entries that come from Brave (ml_subscriber and ml_subscriber_hash), then they don't need to be added to the clean-url list since they'll be removed automatically earlier.

They're not wrong, nor will they cause problems, they're just not necessary.

just a thought, but you might want to leave them in the clean URL list (even if they're duplicates) is that we don't strip query parameters on same-site navigations, so there are at least possible cases where the query params are in the URL, but users still might want them removed.

Good point. I don't think it's going to matter in this particular case since they're email newsletter trackers (therefore will be cross-site), but it may in other cases.
