Overall looks good.
Just something small I noticed - the semantic colors are not correct in all cases:

• in Horizon/Horizon Dark they look like are slightly different
• in Horizon HCB/ HCW the text only tabs should be the same color (all black/ all white), only the small icons should be semantic

1. the parameters are correct, I guess their values are to be updated
2. fixed

• Two click area
  • Separator right padding is -1px, while the spec says it should be 0px?
  • Button is not vertically centered
• Overflow button
  • not vertically centered
  • hover and regular states are changed - regular should be white, hover should be gray

Two click area - the -1px padding is to make it hide on button hover. Centering is fixed
Overflow button - CSS parameters are not updated yet. It will look as designed once they are updated. Centering is fixed
