I'm using the new Summer '20 feature Run Flows in System Mode (https://releasenotes.docs.salesforce.com/en-us/spring20/release-notes/rn_forcecom_flow_fbuilder_system_mode.htm). It works fine in my scratch org - as in after saving the flow it shows 'Running in system mode' at the top(we are using unlocked packages and scratch orgs to develop and deploy changes between scratch orgs using bitbucket pipelines) but when pulling the changes from my scratch org shows no changes at all to the flow XML. Is this new feature packageable?
