Code insights series box hover effect is very strong and somewhat misleading

[felixfbecker]

When hovering over the series box, you get this very strong outline effect (stronger than our focus outlines):

This kind of looks like the element is focused, or at least can be clicked/is interactive. It isn't however, clicking doesn't have an effect. Only the "Edit" and "Delete" texts on the right are clickable (which is also not entirely obvious, because they are black in the redesign).

Heads up @Joelkw @felixfbecker - the "team/code-insights" label was applied to this issue.
