deluge console errors on addition of torrent with semicolon (`;`) in name

[iconoclasthero]

$ deluge-console --version
deluge-console 2.1.1
libtorrent: 2.0.11.0
Python: 3.12.9
OS: Linux 6.13.2-061302-generic

Background: script to create torrents and add them to deluged via deluge-console.

Create a torrent with transmission-cli:

Creating torrent "/library/torrent/Last1, First1; Last2, First2 -- Title, 3_e (1989, 2016).torrent"
2 files, 84.84 MB
1,295 pieces, 65.54 kB each
 done!
torrentfile=/library/torrent/Last1, First1; Last2, First2 -- Title, 3_e (1989, 2016).torrent

The next step is to add the torrent to deluge via deluge-console:

deluge-console "connect $delugehost:$delugeport $delugeuser $delugepass; add -p ${linked@Q} ${torrentfile@Q}"

ValueError: No closing quotation

changing torrentfile to specifically escape the semicolon does not help:

torrentfile=/library/torrent/Last1, First1\; Last2, First2 -- Title, 3_e (1989, 2016).torrent

NB: the @Q wraps the semicolon-containing string in single quotes which I thought should be enough:

echo "${torrentfile@Q}"
'/library/torrent/Last1, First1; Last2, First2 -- Title, 3_e (1989, 2016).torrent'

Also this fails...

$ deluge-console "connect $delugehost:$delugeport $delugeuser $delugepass; add -p ${linked@Q} \"${torrentfile//\;/\\\;}\""

defining "$torrentfile" as also does not work:

torrentfile=/library/torrent/Last1\,\ First1\;\ Last2\,\ First2\ --\ Title\,\ 3_e\ \(1989\,\ 2016\).torrent
