Invalid checkbox is not showing Checked / Unchecked state

[jpaulomotta]

Describe the bug When a validation fails on a check box field, it's impossible to know if it's checked or unchecked later. Both states are using the same light red background.

To Reproduce Steps to reproduce the behavior:

1. Create a model with a checkbox field
2. Fails the validation there for some reason
3. Submit an invalid form
4. Click on checkbox when it's red. It doesn't change its appearance.

Expected behavior The check box would change when it's checked / unchecked
