Wrong Plugin ID when looping throug Plugins

I confirm the issue. This is reproducible with version 1.4 due to 📌 Modify form structure and use core 'states' JS for each access plugin Fixed .

The issue can be reproduced when user_fields_visibility module is enabled. When I select 'user_fields_visibility' plugin, I see the config form for 'custom' plugin...

I also confirm the MR fixes the issue.

Indeed if I check "custom permissions" without this fix then there is nothing happening. With the fix a table of permissions pop up.
I confirm the issue and fix.
