Additional information
This seems to be associated with the paneType parameter, happen on both tab, split and window.
If you delete the 202607161335.md file, the tab we create on step 4 will back to NoteA.
I didn’t test with the window value for the paneType parameter but with tab and split, each time, the note from which the URI was clicked on is indeed also replaced by the brand new unique note (so the new unique note is opened twice) …
