Prbly because it misses the button padding metrics from the top of common :|
Yeah as I said you can put EVERYTHING in the headerbar. And gtk app devs just look for the default paddings of adwaita and apply this

Clicking on the list opens this stack ->


Isn't it supposed to look like that? :thinking:
Do you mean the option button is thinner?

No, the headerbar should not change it's sizes. So the padding of all potential elements must fit the height. We managed to make this happen for mos things. But it looks like we've missed the color picker buttons
@clobrano the button looks thinner because the height gets stretched :)
Ahhhhh sorry, I missed that in the screenshots but it's easy to see in the gif. I thought you meant that the button was a rectangle aka stretched in the headerbar 🤦♂ (too early for me 😄 )
Note: it turned out that this is actually an upstream inconsistency since the min height is not set, should fix this upstream
