studies annotator string gets a URL prefix, not parsed, upon export and re-import via chapter PGN

[Dboingue]

Exact URL where the bug happened

any study, upon chapter re-import containing annotations

Steps to reproduce the bug

Any study with chapter containing annotations by lichess user (study creator at least)
(I was not the creator of the chapter or annotations, if that makes a difference).

1. Export the chapter to PGN
2. add chapter via import PGN of that file
3. browse the new chapter for moves with annotations

What did you expect to happen?

same thing as original chapter in study. The annotator name only and the move, in the text box under the board.

What happened instead?

see screenshots below.
The annotator string displays a non-parsed URL prefix (probably for out-of-lichess traceability)
(https://lichess.org/) / @ / ANNOTATOR

Operating system and browser version
Chrome on some windows (do not want to divulge how old it is)

Good!

Kind of bad!

There is a brand new thread on lichess feedback. This issue here, is for persistence of the reporting of that cosmetic issue.
Bug? could also be a refinement suggestion.
