Fixed.

I see something odd on the gif too.
On hover, the three dot should probably not be seen over the avatar, no?
The contrast is quite problematic. It should be full background colour with the three dot svg on top of it?

I think I don't really understand. When the menu is closed, and one hovers the avatar, the three dots icon shows up. This is how it is now already 🤔

I don't know where this gif comes from, but I think there is something off with it. For me, the three dots have far more contrast, in an app and in the docs:

You're right, I guess it's because I have a dark theme and it's much easier to see the three dot icon there than the light theme tbh.
We can merge as is

Works fine now

Can we add a size/small prop to NcButtoninstead of deep internal classes overrides?
