Save button is grayed out for media files

When clicking on a media file, changing a field, the “save” button is grayed out.

If I cmd+s it becomes normal and then I can click and save. Or cmd+s twice…

Have you tried deleting the cache and cookies?
Also, does an error appear on the console?

No error in the console. Tried again on a web server and it’s fine. This just happens in my local environment.

I can’t reproduce this either.

Do you get the same issue in a fresh Starterkit in your local environment? What is your local environment?
