Confirmed that loading a game via the "Add to Library" button on the analysis page:
...does NOT load annotations (variations, comments, etc.), but loading the game into the library via copying/pasting the pgn from the analysis page DOES load annotations.
The "Add to Library" button on the analysis page definitely needs to transfer ALL saved analysis data, not just the moves from the game.
An annotated game saved into a library does not display the annotation. If one loaded the annotated pgn and saves it into the library the annotation do display.
Here is the screen shot of the analysis report Analysis tab:

Here is the display of the same game pgn loaded on the Analysis page, less the [Link ... ] comment and saved to the library:

Here is the Library display of that game, missing the annotations:
So the bug seems to be analyzed games, when displayed skip over the annotations.
