Cross form rending via ajax, form is missing ViewState

Seems this is an old issue, which was presumably fixed for MyFaces in 2.2 as discussed here https://balusc.omnifaces.org/2011/09/communication-in-jsf-20.html#AjaxRenderingOfContentWhichContainsAnotherForm

and https://github.com/jakartaee/faces/issues/790

Using openliberty with jsf-3.0 feature still has this occurring. Using the workaround outlined by the first link fixes the issue. I believe the same is true for the jsf-2.3 feature as well.
