Global permissions module: defaultGrants "all" doesn't consistently work

Issue Summary

https://ecosystem.atlassian.net/browse/ACJIRA-2624 

our app (https://jxl.app) uses global permissions, and relies on

"defaultGrants": ["all"]

to be available right after installation. Unfortunately, this doesn’t work consistently; customers keep reaching out to us because the global permissions aren’t set correctly.

Please treat this with priority, as this is a major roadblock in our funnel.
