Link style was not applied to the dashboard

Fixes #

Proposed changes

Apply theme to dashboard links.
theme is null when applying the link theme. No exception, but no effect.
This could be considered for 3.5 too.

An alternative to applying the theme is to remove the theme handling here.

You could convert it from a field to a local. It's only used within RefreshContent. Then it can be declared as non-null.
