Hello Wisdom ... love your name ...
Name your portals using Object Name (see Inspector > Position tab > Name).
If you attempt to navigate using Go To Field or Go To Object [ tab panel ] or Go To Portal Row [ Last ] ... it will bite you. See quick demo of the issue here:
Always name the object you wish to go to and save yourself repeated, unexpected problems. :-)
This issue, and not understanding the difference in tab panel stacking order, has caught even great developers off guard.
Nice to meet you, I use your recommed way to try, oh, perfact. I had worked out my mindset.
