I believe that these changes were likely made in error. Servo button controls do not follow the system theme, so system colors should not be used. These changes degraded the look of the buttons, so this change reverts to the previous state. Signed-off-by: Martin Robinson <[email protected]>

This change modified the styling of form controls, which should have been done in a separate change. Instead, this change should have maintained the existing style of form controls by porting the current Servo colors to Stylo or, instead, provided a way for Stylo to override these colors for itself.
