Currently, if you have links or buttons in the header, then scroll down and try to navigate your page by keyboard 'tab', elements in the header will be focused, but the header itself won't appear.
Check my sandbox
This is possibly an accessibility issue and a bug.
Possible solution is just apply 'headroom--pinned' styles on 'headroom--unpinned:focus-within':
.headroom--unpinned:focus-within {
transform: translate3d(0px, 0, 0px) !important;
}
