Add validation to media library

I am almost certain there already exists an issue for this. Can you investigate please?

Changes are made on on 11.x (our main development branch) first, and are then back ported as needed according to the Core change policies → .

This is at the top of the postponed list, was a duplicate ever found?

The title doesn't really seem to match the IS or patch either, wondering what we should do here.

I couldn't find a duplicate but seems like a valid issue. But seems more like a feature request vs a bug
