Hahaha, I had long forgotten about that post (back then I was still a “normal” user)
You’re right, the default button styles are currently overriding every other button style and the outline option isn’t working with the default button
And yes, it is very confusing and that’s why we are going to deprecate the theme style colors (they are back from the early days when there were no color palettes) in one of the next versions (not in 1.4). We already created an internal task for this some time ago.
