A default top property is needed for .health_indicator

[NightJar]

Browsers that aren't Chrome seem to deal with this in interesting manners.
The element is currently positioned absolute with a default right property, but no top property seems to see browsers do as they please with the alignment.

Adding a top: 1.2308rem to the a that is .health-indicator sees the issue solved, however this needs to be done appropriately with scss variables - the value here is the padding-top from the parent h3 that is .pacakge-summary__details-header
