Remove expansion hover animation from status icon buttons
This issue has come up multiple times:
Shifting positioning or size of a hovered element is really bad for usability.
For example, you can see the pipeline view flicker when there's a long branch name.
- Remove animation which expands the button
- Remove caret
- Remove dropdown arrow (not displayed in image)
- Implement new hover/focus/active styles as replacement of animation
left to right: default, hover, active, focus
