Primary buttons are the same color as other buttons

I am facing same issue.
But quick solution is by adding bootstrap classes in 'Submit button CSS classes' filed of webform.
If we will add bootstrap button classes, like - btn-success, btn-warning, btn-info, in 'Submit button CSS classes' filed then button style is changing.

@rhovland
If user wants to add other bootstrap button classes link "btn-success, btn-warning, btn-info" then will be working in template file.
Can we give option in theme setting?

I just wanted to make sure the default core behavior is at least addressed in this theme. The other buttons are outside the scope of this issue.
Users can edit the template of course, but the hours of research to figure out what was wrong and fix it for something as simple as "button vs primary button" isn't a good first use experience for this theme.

I was able to pull this feature request down and test it. Everything looks to be working for me. Marking it as reviewed.

Also agreed that this is RTBC. However the exact same approach is used in ✨ Align default button styles more closely on Drupal core Active but that issue also makes an addition change to fix "Add more" buttons. So I'm marking this as a duplicate of that.
