X-ing a Notebook from "linked notebook" doesn't unlink notes from this Notebook

[streetwriters]

What happened:
I have a note in notebook A, which I want to move to notebook B. So I open properties, linked notebook, then clicked on notebook A (so it shows ❌ at its left circle), and clicked on notebook B (so it shows ✔️).
After saving, turns out, the note gets linked to notebook B (as expected), but also stays linked to notebook A (bug).
Expected behavior:
Note will be unlinked from notebook I ❌ed.

Also, when I only ✔️ notebook B without ❌ing notebook A, I expect the note to move to notebook B, and gets unlinked from A. Just like in desktop in "link notebooks". But turns out, in desktop, when I ✔️ notebook B, notebook A is automatically ❌ed, then what happened is as expected.
