Adding my case details here as this might help ppl in future as I got very useful info from this group.
I got into similar situation to apply Both closed and open [Bridging Open WP] at same time. Closed by my employer and open by myself as I just got my AOR for PR.

Closed WP extension filed on Nov-1, 2019
Open WP filed on Nov-4, 2019
Closed WP extension approved on Feb-7, 2020
Open WP - approved on Feb-10, 2020
hope this helps. Thanks for the one who created this group.
