Space Permission Settings Don't Protect Against Self-Changes

[Windows81]

Steps to reproduce

I use Schildi, though the steps are also reproduceable on Element itself:

1. Navigate to a space's settings.

2. Roles & Permissions » Priviledged Users

Outcome

What did you expect?

For an action that can potentially brick any space where the only admin is you, it's expected that there is a warning popup if you're modifying your own permission level.

What happened instead?

Your role changes right away. If the space had only one admin before, it now has zero admins. Under default settings, that'll essentially brick the entire space and prevent any metadata changes from ever emerging.
