"Merge When Build Succeeds" button is split on mobile
The buttons shouldn't be split like this, since the second button there is a dropdown.
I think this issue was introduced in !4386 (merged).
Considerations to make:
- Make sure other states of the merge request page aren't affected negatively by this, e.g. don't revert the designs implemented in !4386 (merged).
- This can be tested by just messing with the view so that this state is always the one being displayed.
