Estimated code review effort: 2 (Simple) | ~15 minutes Merge Risk: 🔵 Low · up to PageHeader exposes a ref prop but does not forward it to the rendered header element, so consumers relying on that ref may not receive the expected DOM reference. The change is otherwise mergeable with explicit owner follow-up on this bounded API issue. Sequence Diagram(s)sequenceDiagram

Forward the ref to the rendered element.
PageHeaderProps accepts ref, but React 18 does not pass refs to this React.FunctionComponent. PageHeader therefore renders without attaching the ref, so ref.current remains unset. Wrap the component with React.forwardRef and pass the ref to Component. Add a test for the rendered element.

Can we update this to just say "Page header" or something like that so we aren't including the masthead? I put "Custom header" In core, but IMO it's probably better as "Page header". wdyt?

Should this default to a header element? Looking at the RHDS primary navigation, there is no header element included as far as I can tell, and on https://images.redhat.com/, looks like Matt added a <header class="hb-app-header"> element to wrap the global header. It is worth noting, <rh-navigation-primary> has role="navigation". wdyt @thatblindgeye?

Separate problem, but I'm surprised we don't have a bunch of a11y violations from these IDs repeated across the examples.

Tried to get it consistent with patternfly/patternfly#8567, but let me know if I'm missing something here.
