Drag-and-drop table from Catalog to Contents — Unexpected hover-text (edited)

[Bud]

Edited:

I have a standalone table in an ArcGIS Pro 3.0.3 mobile geodatabase. I've dragged the table from Catalog to the Contents pane:

Question:

When dragging-and-dropping to the Contents pane, why does the hover-text say "Copy to Projects.gdb"?

If I understand correctly, I'm not copying anything to my other GDB (a file geodatabase). I'm simply adding my mobile geodatabase table to the map.

Am I missing something?

Thanks.
