"Copy bookmarked lines" doesn't copy bookmarked lines

Description of the Issue

When I bookmark lines, then select Search --> Bookmark --> Copy Bookmarked Lines, nothing is copied and the clipboard is empty.
If it matters, this was after opening a large file and finding that NPP could not remove non-bookmarked lines (noted in this report: https://github.com/notepad-plus-plus/notepad-plus-plus/issues/13442 ), though I did restart NPP.

Steps to Reproduce the Issue

1. Search for text in an open file
2. Bookmark matches for that text
3. Search --> Bookmark --> Copy Bookmarked Lines
4. Paste the copied text into another tab. No text. :(

Expected Behavior

The lines of text which were bookmarked get pasted into the new tab.

Actual Behavior

Nothing is pasted.

Reproduce the issue by opening a file, bookmarking search matches, and using Search → Bookmark → Copy Bookmarked Lines. Trace the menu command responsible for copying bookmarked lines and verify that the selected lines appear in the clipboard when pasted into another tab. Done means the reproduced workflow copies the bookmarked lines instead of leaving the clipboard empty.
