The <PageLoading> does not seem to be clicking into action on the pipelines page, with the result that the loading indicator just stays in a loading state forever, which looks a bit weird. I had a quick look at it but can't make any sense of it. Maybe someone else can.

Seems like PageLoading is not activated on the page at all and so the LoadingIndicator show and hide functions are never called. That's just from a quick scan though, so not really sure.
