In the screen shot below, notice how the "play" button has a grey background and white button. To reproduce the problem, create a new dashboard, click "Controls" and select "Add time slider control".
The play button should have the primary color background because the component sets display="fill" and look like the below screen shot (from 8.5.0). This is a regression that may be caused by #141279
The problem is that background is getting set to grey by this css rule, https://github.com/elastic/eui/blob/main/src/components/form/form_control_layout/_form_control_layout.scss#L95
