Validation error blocks slug field buttons

[jefferyto]

Describe the Bug.

The validation error message for a slug field blocks the Generate and Lock/Unlocks buttons:

There are ways for the user to work around this (the buttons extend below the error message slightly so they are technically still clickable; tabbing with the keyboard to focus the buttons; filling in the Title field to auto-populate the slug field) but it would be better if the buttons or error message can be relocated so they do not overlap.

Reproduction Steps

1. Checkout reproduction repo, npm install, npm run dev
2. Open http://localhost:3000/admin, create first user
3. Create a new Post, click Publish without filling in any fields
