Bug Report: Funnels not aggregating unique users with "Use person properties from the time of the event"

Bug Description

Bug description

The "Event person filtering behavior setting" for an account has 3 settings as show in the screenshot:

Based on the descriptions, it seems that options #2 ("Use person properties from the time of the event") should deduplicate merged user ids the same as option #3 but in testing we are seeing duplicate user counts in funnel analytics.

I may be misunderstanding these settings, but if that is the case then I don't see a way to create funnel graphs with user properties from the time of an event and correct unique users aggregation. Is there another setting of feature that I've missed?

How to reproduce

1. Visit a website using posthog as an anonymous user and perform some pageviews.
2. Login to get identified with a user id and then perform some pageviews.
3. Create a funnel starting with a pageview step. Select to aggregate by unique users
4. Check the number of persons in the first step of the funnel with account set to "Use latest person properties" vs "Use person properties from the time of the event" and see that there are different counts.
5. Additionally, when editing the funnel, you can click the "x persons" text to open a view that shows the number of users who completed this step. When the PostHog account is set to "Use person properties from the time of the event" the list of unique users will show that there were less users than what the funnel count is showing

Additional context

Here are example screenshots from my company's test environment
