header-link-active-background-color not used on jumbo and landing pages

[rommeswi]

I find the header has very inconsistent definitions of background colors.

The most offending case is that jumbo and landing pages make use of --header-link-current-color and --header-link-active-color but not of --header-link-active-background-color. At the very least, there should then be a color definition: --header-link-active-background-color-jumbo (and -landing). Otherwise, making use of the active color creates very inconsistent behavior of the header. Or am I missing something?

There are other issues with landing pages and jumbo pages. Could it be that the jumbo pages use some of the "landing" color definitions? I couldn't figure out exactly what was going wrong but found it hard to achieve the exact desired behavior.
