Is there a way to duplicate sessions from the app-warming issue in Firebase < 8.11.0 via BigQuery?

Question

In Version 8.12.1 of the Firebase Apple SDK an issue with session_start events being logged during app prewarming on iOS 15+ which inserts additional 'session_start' events. I've noticed that as a result of additional session start rows which inserts additional 'ga_session_id' values into the BigQuery table.

ga_session_id is a unique session identifier associated with each event that occurs within a session and is thus created when this additional session_start fires when the app_warming occurs - using the session_number field and calculating session length it's possible to remove sessions with just one session_start and a small session length but this does not seem to reduce the overall count of sessions by much.

This has impacted the reported number of sessions when querying the BigQuery table when counting distinct user_psuedo_id||ga_session_id.

Is there a way to isolate these sessions in a separate table or constrict them from the query using an additional clause in said query to remove the sessions which are not truly sessions.

A simplified version of said query I'm using:

   with windowTemp as 
    (
        select
            PARSE_DATE("%Y%m%d",event_date) as date_formatted,
            event_name,
            user_pseudo_id,
            (select value.int_value from unnest(event_params) where key = 'ga_session_id') as session_id  
        from
            `firebase-XXXX.analytics_XXX.events_*`
        where
            _table_suffix between '20210201' and format_date('%Y%m%d',date_sub(current_date(), interval 1 day))
        group by 
        1,2,3,4
    )

    SELECT 
        date_formatted,
        Count(DISTINCT user_pseudo_id) AS users,
        Count(DISTINCT Concat(user_pseudo_id,session_id)) AS sessions,
    FROM
        windowTemp 
    GROUP by 1
    ORDER BY 1
