So I guess our only solution now is to glide.sc.va.render_type.legacy = true....Not ideal...That stops the inline filling out of a request form directly in the agent which is useful for Microsoft Teams integration among other places.

I am not sure why ServiceNow would, by default, would open a "Request this item" link to a Catalog Item in the Virtual Agent in some Virtual Agent catalog window/tab as opposed to just opening the actual catalog item request form in the active default Portal.  Seems like they created more work for themselves without needing to.
